Second Quarter Results

Total net revenue for the second quarter of 2006 was $2.3 million
as compared to $3.5 million in the first quarter of 2006 and $3.1
million recorded in the second quarter of 2005. The second quarter
revenue guidance was recently revised by the Company as a result of a
license agreement with a major IDM that was delayed into the third
quarter. That license agreement was signed on July 24, 2006.

Second quarter total revenue included licensing revenue of $1.7
million as compared to $2.3 million in the first quarter of 2006 and
$1.9 million in the second quarter of 2005. Royalty revenue for the
second quarter was $639,000 compared to $1.3 million in the previous
quarter and $1.1 million in the same period a year ago. The Company
recorded licensing revenue from 13 different chip development projects
compared to 12 in the first quarter and royalty revenue from 18
different licensees compared to 19 in the previous quarter.

“We continue to make solid progress on the strategic initiatives
announced earlier this year. We signed multiple CLASSIC Macro
licensing deals during the quarter, initiated programs with
semiconductor manufacturers at the advanced 65 nanometer process
geometry, and further broadened our relationship with Nintendo and
NEC,” commented Chet Silvestri, Chief Executive Officer of MoSys.

“Our CLASSIC Macro program continues to attract new customers as
well as generating repeat business with existing customers. CLASSIC
Macros enable our customers to move more rapidly from the development
stage to the production stage, thereby shortening time-to-market. This
advantage allows customers to reach volume production faster, which is
critical in the highly competitive consumer electronics market. As a
result, we have had several existing customers engage with us for
additional future projects.”

Also during the quarter, MoSys completed the research and
development work for porting the 1T-SRAM technology to the 65nm
process node and initiated macro design work with pure-play foundries.
In addition, in July the Company signed a licensing and royalty
agreement with a major IDM who will utilize MoSys 1T-SRAM technology
in their 65nm process node.

Mr. Silvestri concluded, “We are pleased with the progress we have
made in our 65nm initiatives — both for our CLASSIC Macros and our
technology licensing. We expect these initiatives to drive increased
licensing revenue in the latter part of 2006 and to drive our royalty
growth in 2007. Also during 2007 we anticipate strong royalty growth
from the success of Nintendo’s Wii(TM) video game console.”

In accordance with Generally Accepted Accounting Principles (GAAP)
the second quarter gross margin percentage was 84 percent, compared to
90 percent in the first quarter of 2006 and 80 percent in the second
quarter of 2005. The sequential decrease in gross margin was mainly
due to the decrease in royalty revenue relative to licensing revenue.

Total operating expenses for the second quarter were $4.9 million,
which included approximately $570,000 in legal expenses related to the
UniRAM litigation as the Company aggressively seeks to resolve this

The GAAP net loss for the quarter was $2.1 million, or ($0.07) per
share, including stock-based compensation expense under Statement of
Financial Accounting Standard No. 123R (FAS 123R) of $624,000. This
compares to a net loss of $974,000, or ($0.03) per share, in the first
quarter of 2006 and a net loss of $579,000, or ($0.02) per share, in
the second quarter of 2005.

The non-GAAP net loss for the second quarter, which excludes the
total stock-based compensation charges of $624,000, was $1.4 million,
or ($0.05) per share. Per share amounts were computed using 31,293,000
shares outstanding for the quarter. A reconciliation of GAAP results
to non-GAAP results is provided in the financial statement tables
following the text of this press release.

Cash, cash equivalents and both long and short-term investments
totaled approximately $84.5 million as of June 30, 2006 compared to
approximately $85.4 million as of March 31, 2006.

Business Outlook

MoSys’ Chief Executive Officer and Chief Financial Officer will

Use of Non-GAAP Financial Measures

To supplement MoSys’ consolidated financial statements presented
in accordance with GAAP (Generally Accepted Accounting Principles),
MoSys uses non-GAAP financial measures that exclude from the income
statement the effects of stock-based compensation and the effects of
our adoption of SFAS 123R upon the number of diluted shares used in
calculating non-GAAP loss per share. MoSys’ management believes that
the presentation of these non-GAAP financial measures is useful to
investors and other interested persons because they are one of the
primary indicators MoSys’ management uses for planning and forecasting
future performance. In addition, MoSys believes that it is important
to provide investors and other interested persons with a consistent
basis for comparison between quarters, particularly in light of the
Company’s adoption of the modified prospective transition method under
SFAS 123R, which requires application of the accounting standard as of
January 1, 2006 but not for prior periods. Investors are encouraged to
review the reconciliation of these non-GAAP financial measures to the
comparable GAAP results, which is provided in a table immediately
below the Condensed Consolidated Statements of Operations. For
additional information regarding these non-GAAP financial measures,
and management’s explanation of why it considers such measures to be
useful, refer to the Form 8-K dated August 2, 2006 that we have
submitted to the Securities and Exchange Commission.

About MoSys, Inc.

Founded in 1991, MoSys, Inc. (Nasdaq:MOSY), develops, licenses and
markets innovative memory technologies for semiconductors. MoSys’
patented 1T-SRAM technologies offer a combination of high density, low
power consumption, high speed and low cost unmatched by other
available memory technologies. The single transistor bit cell used in
1T-SRAM memory results in the technology achieving much higher density
than traditional six transistor SRAMs while using the same standard
logic manufacturing processes. 1T-SRAM technologies also offer the
familiar, refresh-free interface and high performance for random
address access cycles associated with traditional SRAMs. In addition,
these technologies can reduce operating power consumption by a factor
of four compared with traditional SRAM technology, contributing to
making them ideal for embedding large memories in System-on-Chip (SoC)
designs. MoSys’ licensees have shipped more than 100 million chips
incorporating 1T-SRAM embedded memory technologies, demonstrating
excellent manufacturability in a wide range of silicon processes and
applications. MoSys is headquartered at 755 N. Mathilda Avenue,
Sunnyvale, California 94085. More information is available on MoSys’
