WALTHAM, Mass. and SUNNYVALE, Calif. (May 24, 1999)
— Lexra,
a leading developer of processor cores for embedded applications,
and MoSys, a premier supplier of leading-edge memory products and
licensable memory cores, today announced a partnership to jointly
market Lexra’s RISC and DSP cores with MoSys’ embedded SRAM for
System-On-Chip (SOC) designs. The companies will jointly produce
a test chip that contains Lexra’s ¹LX5280 RISC-DSP core and MoSys’

Embedded RISC processors and DSPs need increasingly large amounts
of on-chip memory, but must remain within a tight power consumption
and die size budget. By combining Lexra’s 32-bit RISC and DSP cores
with MoSys’ ultra-high density, low power 1T-SRAM, SOC designers
can achieve unprecedented performance with very low power consumption
and small die area. The Lexra-MoSys test chip, which will combine
Lexra’s LX5280 RISC-DSP core with 2Mbits of MoSys’ 1T-SRAM, will
be fabricated on a 0.18-micron process at a mutual foundry partner.

“We are excited to be working with Lexra,” stated Mark-Eric
Jones, vice president and general manager, intellectual property
at MoSys. “Lexra¹s leading RISC-DSP core and MoSys’ unique
1T-SRAM memory each achieve industry-leading performance, die area
and power consumption characteristics. Combined, they represent
an outstanding embedded solution for customers.”

“We’re pleased to partner with MoSys, a leader in memory
technology,” said Charlie Cheng, president and CEO of Lexra.
“This test chip will demonstrate to our customers a highly
compelling channel for delivering innovative DSP and other embedded
processing solutions.”

The 0.18-micron test chip will be available to mutual licensees
of Lexra and MoSys in Q1, 2000. It will include the LX5280 plus
2Mbits of 1T-SRAM, organized as 128KB of instruction RAM and 128KB
of data RAM. The chip will run at speeds of 200MHz to 266MHz, with
a die size of less than 36mm2 and power consumption of less than

Lexra’s family of RISC and DSP cores lead the industry in ease-of-use
and portability, while comparing favorably to industry leaders in
performance, die size and power consumption. The LX5280 32-bit RISC-DSP
core executes the MIPS I® instruction set* and Lexra’s RADIAXTM
DSP extension, and delivers performance of 400 MMACs (Million Multiply-Accumulate
instructions per second).

MoSys’ innovative 1T-SRAM offers one-third the die size and one-fourth
the power consumption of other leading-edge SRAM technologies, and
can be implemented on standard logic semiconductor processes.
