TwinMOS has completed the R&D of DDRII-533 SO-DIMM for the brand new Sonoma platform—the next generation Centrino platform Napa, comprising the Calistoga chipset and the next generation wireless LAN technology Golan, to be introduced into the market at the end of 2005. Moreover, TwinMOS Technologies is validating the compatibility of the Calistoga chipset of Napa in cooperation with Intel. TwinMOS Technologies has designed the DDRII-533 SO-DIMM for Intel’s Sonoma platform in accordance with the 4-bit Prefetch architecture of DDRII specification in order to burst transfer bandwidth to 4.3GB/sec and has extensively reduced the power consumption of the product to 1.8V to lower the overall power consumption of notebook PCs and thereby extend the battery life.

TwinMOS PC2 4300 TwinMOS DDRII 533 SO DIMM For Sonoma

As the first world-leading memory maker to pass the DDR-II module
certification of Intel Laboratory Taiwan when the product was first introduced
to the market, TwinMOS Technologies Inc has completed the R&D of DDRII-533 SO-DIMM
for the brand new Sonoma platform—the next generation Centrino platform Napa,
comprising the Calistoga chipset and the next generation wireless LAN technology
Golan, to be introduced into the market at the end of 2005. Moreover, TwinMOS
Technologies is validating the compatibility of the Calistoga chipset of Napa in
cooperation with Intel.

While high-speed-transfer is the target of DDRII technology, in addition to
following the JEDEC specifications, TwinMOS Technologies has designed the
DDRII-533 SO-DIMM for Intel’s Sonoma platform in accordance with the 4-bit
Prefetch architecture of DDRII specification in order to burst transfer
bandwidth to 4.3GB/sec. Secondly, TwinMOS Technologies has extensively reduced
the power consumption of the product to 1.8V to lower the overall power
consumption of notebook PCs and thereby extend the battery life. Thirdly, the
ODT (On Die Termination) technology can reduce noise interference to enhance
data accuracy by maintaining the waveform of signals. The OCD (Off Chip Driver)
technology can improve the integrity of data transfer signals. Together with
TwinMOS ISO9001/ISO14001-accredited processes, the DDRII-533 SO-DIMM from
TwinMOS Technologies is both performance- and quality-assured.

As TwinMOS Technologies has been the major DRAM module supplier of world-leading
system manufacturers, all DDRII modules from TwinMOS Technologies have been
mass-produced with lead-free processes as a response to the global lead-free
process campaign. TwinMOS Technologies also requests PCB, die and soldering
material suppliers to follow the standards and requirements of Europe, the USA,
Japan and China.
