TwinMOS launches DDR2 (240-pin) memory modules

TwinMOS, a leading memory module maker, has announced the release of DDR2 memory modules for desktop PCs and servers to offer users a brand-new experience for next-generation computer platforms.

TwinMOS, in close cooperation with JEDEC (the Joint Electron Device Engineering Council), as well as a number of DRAM and motherboard manufacturers, is one of the first companies in Taiwan to be passed by Intel Taiwan Lab. for its DDR2 modules. This passing demonstrates the company's continued effort in promoting mainstream memory standards. The products are released amid surging demand for DDR2, the next generation of memory modules developed by Intel and several DRAM foundries. DDR2, made with advanced manufacturing and chip packaging technologies, boasts high performance and low power consumption. It has given rise to a new wave of motherboards and memory modules.

TwinMOS' DDR2 modules are made with the newest 0.1-micron manufacturing process in Fine-Pitch Ball Grid Array (FBGA) chip packages technique, which provides several features. DDR2 allows for faster data transmission. It transmits twice as much data as DDR, between 533Mbps to 667Mbps to meet the demand of high data bandwith applications. In addition, DDR2 requires a lower power consumption. DDR2 runs at a supplied voltage of 1.8V, which is lower than DDR SDRAM's 2.5V, to enable less power consumption and more effective heat dissipation. With a higher data density in FBGA chip packages, the DDR2 module has only half the size of chips made in TSOP packages. This allows more DDR2 chips to be mounted on a PCB, increasing capacity.

TwinMOS has released three kinds of DDR2 modules. It has a DDR2 533MHz, 240-pin, CL4 Unbuffered DIMM for desktop PCs. There is a DDR2 667MHz, 240-pin, CL4 Unbuffered DIMM for over-clocking applications. The third module is a DDR2 400MHz, 240-pin, CL3 Registered DIMM with ECC for servers.

TwinMOS has a close relationship with upstream DRAM chip foundries and downstream M/B manufacturers to form a seamless supply chain. TwinMOS insists its DDR2 be passed by Intel Taiwan Lab. before it releases the products. TwinMOS can be found at Hall 1, D710/714.
