of 6,000,000 shares of the Registrant&#146;s Common Stock which may be offered
pursuant to the MoSys,&nbsp;Inc. 2010 Equity Incentive Plan or the MoSys,&nbsp;Inc.
Employee Stock Purchase Plan.&#160; Of the
6,000,000 shares of Common Stock being registered hereunder, 1,923,817 shares
(the &#147;Prior Shares&#148;) are carried forward from registration statements on Form&nbsp;S-8
filed by the Registrant with the Securities and Exchange Commission (the &#147;SEC&#148;)
on June&nbsp;29, 2001 (333-64302), March&nbsp;27, 2003 (333-104071), September&nbsp;15,
2004 (333-118992), March&nbsp;16, 2005 (333-123364), March&nbsp;16, 2006

the Prior Shares were originally registered for issuance pursuant to the MoSys,&nbsp;Inc.
Amended and Restated 2000 Stock Option and Equity Incentive Plan (the &#147;Prior
Incentive Plan&#148;), and the filing fee paid by the Registrant with respect to the
registration of such shares was $63.26.&#160;
The remaining 421,578 Prior Shares were originally registered for
issuance pursuant to the MoSys,&nbsp;Inc. 2000 Employee Stock Purchase Plan
(the &#147;Prior ESPP,&#148; and together with the Prior Incentive Plan, the &#147;Prior Plans&#148;),
and the filing fee paid by the Registrant with respect to the registration of
such shares was $37.87.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Section&nbsp;145
of the Delaware General Corporation Law (the &#147;DGCL&#148;) authorizes a court to
award, or a corporation&#146;s board of directors to grant, indemnity to any person
who is made a party to any third-party action, suit or proceeding (other than
an action by or in the right of the corporation) on account of being a current
or former director, officer, employee or agent of the corporation (or serving
at the request of the corporation in such capacity for another corporation,
partnership, joint venture, trust or other enterprise) against expenses,
including attorney&#146;s fees, judgments, fines and amounts paid in settlement
actually and reasonably incurred by him or her in connection with the action,
suit or proceeding, if (1)&nbsp;the person acted in good faith and in a manner
reasonably believed to be in the best interests of the corporation (or in some
circumstances, at least not opposed to its best interests), and (2)&nbsp;in a
criminal action or proceeding, the person had no reasonable cause to believe
his or her conduct was unlawful.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
DGCL also permits indemnification by a corporation under similar circumstances
for expenses (including attorneys&#146; fees) actually and reasonably incurred by
such persons in connection with the defense or settlement of a derivative
action or suit, except that no indemnification may be made in respect of any
claim, issue or matter as to which the person is adjudged to be liable to the
corporation unless the Delaware Court of Chancery or the court in which the
action or suit was brought determines upon application that the person is
fairly and reasonably entitled to indemnity for the expenses which the court
deems to be proper. To the extent that a current or former director, officer,
employee or agent is successful in the defense of such an action, suit or
proceeding, the corporation is required by the DGCL to indemnify such person for
reasonable expenses incurred thereby. Expenses (including attorneys&#146; fees)
incurred by such persons in defending any action, suit or proceeding may be
paid in advance of the final disposition of such action, suit or proceeding
upon receipt of an undertaking by or on behalf of that person to repay the
amount if it is ultimately determined that person is not entitled to be so
indemnified.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">As
permitted by the DGCL, our Bylaws provide that the Registrant shall indemnify
its directors and officers, and may indemnify its employees and other agents,
to the fullest extent permitted by law. The Bylaws also permit the Registrant
to secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions in such capacity,
regardless of whether the Bylaws would permit indemnification. The Registrant
has obtained officer and director liability insurance with respect to
liabilities arising out of certain matters, including matters arising under the
Securities Act.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
Registrant also has entered into agreements with its directors and executive
officers that, among other things, indemnify them for certain expenses
(including attorneys&#146; fees), judgments, fines and settlement amounts incurred
by them in any action or proceeding, including any action by or in the right of
the Registrant, arising out of such person&#146;s services as a director or officer
of the Registrant, any subsidiary of the Registrant or any other company or
enterprise to which the person provides services at the request of the

as indemnification for liabilities arising under the Securities Act of 1933 may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.</font></p>

EXPLANATORY NOTE
This
Registration Statement on Form S-8 covers the registration of an aggregate
of 6,000,000 shares of the Registrant's Common Stock which may be offered
pursuant to the MoSys, Inc. 2010 Equity Incentive Plan or the MoSys, Inc.
Employee Stock Purchase Plan.  Of the
6,000,000 shares of Common Stock being registered hereunder, 1,923,817 shares
(the "Prior Shares") are carried forward from registration statements on Form S-8
filed by the Registrant with the Securities and Exchange Commission (the "SEC")
on June 29, 2001 (333-64302), March 27, 2003 (333-104071), September 15,
2004 (333-118992), March 16, 2005 (333-123364), March 16, 2006
(333-132492), March 13, 2007 (333-141264), March 17, 2008
(333-149756) and March 16, 2009 (333-157964) (collectively, the "Prior
Registration Statements").  1,502,289 of
the Prior Shares were originally registered for issuance pursuant to the MoSys, Inc.
Amended and Restated 2000 Stock Option and Equity Incentive Plan (the "Prior
Incentive Plan"), and the filing fee paid by the Registrant with respect to the
registration of such shares was $63.26. 
The remaining 421,578 Prior Shares were originally registered for
issuance pursuant to the MoSys, Inc. 2000 Employee Stock Purchase Plan
(the "Prior ESPP," and together with the Prior Incentive Plan, the "Prior Plans"),
and the filing fee paid by the Registrant with respect to the registration of
such shares was $37.87.
Both
of the Prior Plans were terminated on June 30, 2010.  Accordingly, on July 27, 2010, the
Registrant filed a post-effective amendment to each of the Prior Registration
Statements in order to remove from registration the Prior Shares covered by
such Prior Registration Statement.  The
post-effective amendments described the Registrant's intention to carry forward
the Prior Shares and the associated filing fees to this newly filed
Registration Statement, in accordance with Instruction E of Form S-8 and
the guidance provided by the Division of Corporation Finance under G.89 of the
Manual of Publicly Available Telephone Interpretations.

Item 6.
Indemnification of Directors and
Officers.
Section 145
of the Delaware General Corporation Law (the "DGCL") authorizes a court to
award, or a corporation's board of directors to grant, indemnity to any person
who is made a party to any third-party action, suit or proceeding (other than
an action by or in the right of the corporation) on account of being a current
or former director, officer, employee or agent of the corporation (or serving
at the request of the corporation in such capacity for another corporation,
partnership, joint venture, trust or other enterprise) against expenses,
including attorney's fees, judgments, fines and amounts paid in settlement
actually and reasonably incurred by him or her in connection with the action,
suit or proceeding, if (1) the person acted in good faith and in a manner
reasonably believed to be in the best interests of the corporation (or in some
circumstances, at least not opposed to its best interests), and (2) in a
criminal action or proceeding, the person had no reasonable cause to believe
his or her conduct was unlawful.
The
DGCL also permits indemnification by a corporation under similar circumstances
for expenses (including attorneys' fees) actually and reasonably incurred by
such persons in connection with the defense or settlement of a derivative
action or suit, except that no indemnification may be made in respect of any
claim, issue or matter as to which the person is adjudged to be liable to the
corporation unless the Delaware Court of Chancery or the court in which the
action or suit was brought determines upon application that the person is
fairly and reasonably entitled to indemnity for the expenses which the court
deems to be proper. To the extent that a current or former director, officer,
employee or agent is successful in the defense of such an action, suit or
proceeding, the corporation is required by the DGCL to indemnify such person for
reasonable expenses incurred thereby. Expenses (including attorneys' fees)
incurred by such persons in defending any action, suit or proceeding may be
paid in advance of the final disposition of such action, suit or proceeding
upon receipt of an undertaking by or on behalf of that person to repay the
amount if it is ultimately determined that person is not entitled to be so
indemnified.
As
permitted by the DGCL, our Bylaws provide that the Registrant shall indemnify
its directors and officers, and may indemnify its employees and other agents,
to the fullest extent permitted by law. The Bylaws also permit the Registrant
to secure insurance on behalf of any officer, director, employee or other agent
for any liability arising out of his or her actions in such capacity,
regardless of whether the Bylaws would permit indemnification. The Registrant
has obtained officer and director liability insurance with respect to
liabilities arising out of certain matters, including matters arising under the
Securities Act.
The
Registrant also has entered into agreements with its directors and executive
officers that, among other things, indemnify them for certain expenses
(including attorneys' fees), judgments, fines and settlement amounts incurred
by them in any action or proceeding, including any action by or in the right of
the Registrant, arising out of such person's services as a director or officer
of the Registrant, any subsidiary of the Registrant or any other company or
enterprise to which the person provides services at the request of the
Registrant.

Item 8.
Exhibits.
See
Exhibit Index which is incorporated herein by reference.
Item 9.
Undertakings.
The
undersigned Registrant hereby undertakes:
(1)
To file, during
any period in which offers or sales are being made, a post effective amendment
to this registration statement:
(i)            To include any
prospectus required by section 10(a)(3) of the Securities Act;
(ii)           To reflect in the prospectus any
facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set forth in
the registration statement;
II-2
(iii)          To include any material information
with respect to the plan of distribution not previously disclosed in the
registration statement or any material change to such information in the
registration statement;
Provided however
, that paragraphs (i) and
(ii) above do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed with or furnished to the SEC by the Registrant pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.
(2)           That, for the purpose of determining
any liability under the Securities Act, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
(3)           To remove from registration by means
of a post-effective amendment any of the securities being registered which
remain unsold at the termination of the offering.
(4)           That, for the purpose of determining
liability of the registrant under the Securities Act to any purchaser in the
initial distribution of the securities, the undersigned registrant undertakes
that in a primary offering of securities of the undersigned registrant pursuant
to this registration statement, regardless of the underwriting method used to
sell the securities to the purchaser, if the securities are offered or sold to
such purchaser by means of any of the following communications, the undersigned
registrant will be a seller to the purchaser and will be considered to offer or
sell such securities to such purchaser:
(i)            Any preliminary prospectus or
prospectus of the undersigned registrant relating to the offering required to
be filed pursuant to Rule 424;
(ii)           Any free writing prospectus relating
to the offering prepared by or on behalf of the undersigned registrant or used
or referred to by the undersigned registrant;
(iii)          The portion of any other free writing
prospectus relating to the offering containing material information about the
undersigned registrant or its securities provided by or on behalf of the
undersigned registrant; and
(iv)          Any other communication that is an
offer in the offering made by the undersigned registrant to the purchaser.
The
undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
Insofar
as indemnification for liabilities arising under the Securities Act of 1933 may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
