Samsung samples 128Mbit DDR SDRAM
Samsung Semiconductor Inc. today debuted a 128Mbit DDR SDRAM designed for graphics and high-speed networks that it says is able to process data at 3.2Gbytes/sec. Samsung�s latest DDR SDRAM device operates at a clock speed of 400MHz, transmitting data at 800Mbits/sec. The device also processes data 30 percent faster than that of the 300MHz DDR SDRAM, the company said. (Electronic News)

JEDEC may not approve 400MHz DDR as standard
During the first-ever JEDEX conference, a representative from JEDEC outlined the future roadmap for the 'mainstream' DRAM market, disclosing that the organization 'may or may not' ratify the 400-MHz version of the double-data-rate (DDR) SDRAM technology as a standard. The disclosure is bound to upset Micron, Samsung and other DRAM makers, many of which are just rolling out their first engineering samples of DRAMs, based on the so-called DDR400 standard.

Micron Technology, Inc., announces DDR400 device
Micron Technology, Inc., today announced it delivered its first industry samples of 400MHz DDR SDRAM memory devices to Silicon Integrated Systems Corporation (SiS) and the devices qualified on the SiS648 chipset. DDR400 devices deliver the faster speeds needed to keep pace with advanced microprocessors and graphics subsystems expected to be available late this year. (e-inSITE)
Samsung sampling DDR400 to PC chipset companies now
As the newest addition to Samsung's DDR SDRAM portfolio, the 400Mbps (200MHz) DDR devices, available in 128Mb and 256Mb densities, offer three times the performance of Single-Data-Rate PC 133 SDRAM and 50 percent higher performance than DDR266. Samsung delivered engineering samples of its new DDR400 to major PC chipset companies, including NVIDIA, SiS and VIA, early this year and has received positive feedback on their performance.

Rambus downplays Intel's growing interest in DDR
Despite the continued proliferation of double-data-rate (DDR) SDRAM in Intel Corp.'s technology roadmap, memory interface designer Rambus Inc. insists that its relationship with the processor giant is alive and well. (Electronic Buyers' News)
Faster DDR memory to move into mainstream shipments
With Rambus Dynamic RAM now firmly established as a niche memory product, Double Data Rate Synchronous DRAM is set to become the most commonly used PC memory this year, with shipments of DDR chips soon to exceed those of low-end SDRAM chips. But users should be cautious when purchasing faster DDR333 memory as not all chips conform with standards defined by an industry group. (PC World)
Hynix raises 128M SDRAM contract prices to 4 usd
Hynix has raised contract prices about twice a month since December, reflecting a tight supply situation, and recently said it will allocate its memory chips only to its long-term customers. (e-inSITE)
Nvidia reportedly will introduce DDR chipset
The Santa Clara-based company is expected to roll out the chip next month, sources said. The nForce 415-D represents the company first non-integrated chip set line, that is, a core-logic product without graphics. (Electronic Buyers' News)
Samsung signs DDR supply pact with Microsoft for Xbox
Samsung Semiconductor, Inc. today announced an agreement with Microsoft Corp. under which Samsung will continue to supply DDR SDRAM memory used in the Xbox video game system. Each Xbox contains four 128Mb (4Mx32) DDR SDRAM devices, optimized for graphics applications, providing a total of 64 Megabytes of system memory. (Electronic Buyers' News)
Sorting out the DDR food fight
As if the DRAM industry didn't have enough turmoil what with consolidations and wild price fluctuations, attention is now being diverted by the ongoing spat between the Advanced DRAM Technology alliance and JEDEC over the future of double-data-rate (DDR) memory. (Electronic Buyers' News)
