SUNNYVALE, Calif.–(BUSINESS WIRE)–Jan. 28, 2004–Monolithic
System Technology, Inc. (MoSys), (Nasdaq:MOSY) today reported
financial results for its fourth quarter and fiscal year ended
December 31, 2003.

Fourth Quarter Highlights

  • Generated new orders exceeding $5 million in licensing fees in
    the fourth quarter
  • Signed technology license for 1T-SRAM-Q with Fujitsu
  • Agilent signed 1T-SRAM(R) License Agreement
  • Licensed 1T-SRAM macro to Sanyo

Fourth Quarter Results

Total net revenue in the fourth quarter was $3.4 million compared
to $7.9 million of net revenue for the same period a year ago. Total
net revenue for the quarter consisted of $1.9 million from licensing,
$1.1 million in royalties and approximately $334,000 in product
revenue. This compares to licensing revenue of $3.3 million, royalty
revenue of $4.0 million and product revenue of $599,000 in the fourth
quarter of 2002.

The gross margin percentage in the fourth quarter of 2003 was 80%
compared to 87% in the same quarter a year ago.

The net loss for the quarter was $415,000, or a loss of $0.01
diluted earnings per share, compared to net income of $4.1 million, or
$0.13 fully diluted earnings per share in the same period last year.
The fourth quarter 2003 diluted earnings per share were computed using
30,704,000 shares.

“Our fourth quarter results were impacted by the schedule delays
of new design projects by our customers,” commented Dr. Fu-Chieh Hsu,
CEO of MoSys. “In fact, R & D spending by our customers had remained
cautious throughout 2003 which has resulted in a lower level of new
design projects and fewer existing products being placed into
production than we had anticipated at the beginning of the year.
However, we are beginning to see an improvement in the funding for new
projects, as evidenced by the new orders generated during the fourth
quarter. We anticipate recognizing the revenue from these new licenses
during 2004.”

Despite the net loss, the company generated $1.5 million of net
cash from operations in the quarter increasing cash, equivalents and
investments, both short and long term to $85.8 million at year-end.

Fiscal 2003 Results

For fiscal year 2003, net revenue was $19.2 million compared to
the $27.8 million reported in fiscal 2002. Net income in 2003 was $2.5
million, compared to net income of $12.4 million reported in 2002. Net
income in the year was equal to 13.0% of net revenue compared to 44.5%
of net revenue in 2002. Fully diluted earnings per share in the year
were $0.08 compared to $0.40 in the prior year. Fully diluted 2003
earnings per share were computed using 30,998,000 shares.

Dr. Hsu further commented, “During 2003, we continued to expand
relationships with existing customers and entered into license
agreements with several significant new customers. Working closely
with our existing and new foundry partners, we have broadened the
range of standard logic process alternatives available for our
licensees. We have entered 2004 with significant momentum and a robust
pipeline of new and existing design projects.

About MoSys

Founded in 1991, MoSys (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 four or 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
50 million chips incorporating 1T-SRAM embedded memory technologies,
demonstrating excellent manufacturability in a wide range of silicon
processes and applications. MoSys is headquartered at 1020 Stewart
Drive, Sunnyvale, California 94085. More information is available on
MoSys’ website at http://www.mosys.com.
