SAMSUNG VOLUME SHIPPING DDR400 PC3200 MODULES NOW.Samsung Semiconductor, Inc. has announced that it is first to volume ship Double-Data-Rate 400Mbps SDRAM (Synchronous DRAM) A type of dynamic RAM (DRAM) memory chip that has been widely used since the late 1990s. SDRAM chips eliminated wait states by dividing the chip into two cell blocks and interleaving data between them. (DDR (Double Data Rate) Refers to an SDRAM memory chip that increases performance by doubling the effective data rate of the frontside bus. For more details, see SDRAM. DDR - Double Data Rate Random Access Memory 400) modules in 128MB, 256MB and 512MB densities. As the newest addition to Samsung's DDR SDRAM See DDR. portfolio, the 400Mbps (200MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. ) DDR devices are ideal for use as PC system main memory, offering three times the performance of Single-Data-Rate PC 133 SDRAM and 50 percent more bandwidth than mainstream DDR266. The volume availability now of these high-speed memory modules further strengthens Samsung's position as the leading producer of DDR SDRAM memory devices. Samsung is ramping up to meet the growing market demand for this high-performance memory technology. Early this year, Samsung was first to deliver engineering samples of DDR400 to major PC chipset A set of chips that provides the interfaces between all of the PC's subsystems. It provides the buses and electronics to allow the CPU, memory and input/output devices to interact. companies, including NVIDIA, SiS and VIA. The devices have received positive feedback and leading-edge chipsets supporting DDR400 will soon be available. "With Samsung's DDR400, chipset manufacturers and their customers are the real winners as they benefit from this extremely high-performance memory," said Tom Quinn, Samsung Semiconductor, Inc.'s vice president of marketing. "Samsung is totally committed to serving our customers by being first-to-market with leading-edge DDR SDRAM memory products." Samsung is the industry's DDR SDRAM technology leader. In 2000, it was first to mass-produce DDR266. In August 2001, the company was first to commence mass production of DDR333 and now supports 128MB, 256MB and 512MB modules. Samsung is also currently the world's largest supplier of DDR memory devices, with more than a 50 percent share of the DDR333 market. It has the highest number of industry-validated memory modules available. The company has been the DDR technology leader since July 1997, when it first proposed the bi-directional DDR SDRAM standard to JEDEC The division of the Electronic Industries Alliance (EIA) that deals with semiconductor standards (officially, the JEDEC Solid State Technology Association of EIA). JEDEC was formed in 1958 when the Joint Electron Tube Engineering Council (JETEC) split into two Joint Electron Device and demonstrated the first DDR silicon in a 64Mb device. Samsung plans to continue its leadership role in memory by being first-to-market with leading-edge devices in a wide range of configurations and densities. Samsung DDR400 PC3200 modules are available through distribution. The 128MB and 256MB modules are shipping now. Part numbers are M368L1713DTL DTL Detail DTL Drift Tube Linac DTL Diode-Transistor Logic DTL Designated Transit List (Sprint-ATM) DTL Deferred Tax Liability (finance/accounting) DTL Deputy Team Leader for the 128MB module and M368L3313DTL for the 256MB module. The 512MB module, part number M368L6423DTL, will be available late May. |
