pomp: It seems that Intel is putting out a higher performance PC133 standard for use by computer industry. Bilow will be crowing all night with latency improvements of 34% of 2-2-2 PC133 DRAM over 3-3-3 PC133 DRAM. john micron.com MICRON TECHNOLOGY, INC., ANNOUNCES AVAILABILITY OF 133MHZ 2-2-2 SDRAM COMPONENTS AND MODULES Micron first to meet faster 2-2-2 specification Boise, Idaho, May 31, 2000 - Micron Technology, Inc., today announced samples of industry standard 133MHz 2-2-2 synchronous DRAM (SDRAM) registered and unbuffered DIMM modules in densities ranging from 32MB to 512MB. Micron is also accepting orders for production volumes of 133MHz 2-2-2 SDRAM components and associated modules. "Micron's 133MHz 2-2-2 SDRAM is compatible with all chipsets using 133MHz 3-3-3 SDRAM modules," said Kit Fawcett, Micron's DRAM Product Marketing Manager. "These faster SDRAM modules provide a quick and painless way to improve the system-level performance of platforms using existing PC133 SDRAMs. Micron is reducing key access parameters in our 133MHz modules, effectively boosting chipset performance without any design change required." The most noticeable improvement with 133MHz 2-2-2 SDRAMs over 133MHz 3-3-3 SDRAMs is the lead-off latency. "Although both speed options provide the same peak burst rate, PC133 2-2-2 offers a lead-off latency of only 30 nanoseconds," said Chris Johnson, Micron SDRAM Applications Engineer. "This is a 34 percent improvement over the 45 nanosecond lead-off latency available from PC133 3-3-3 SDRAM and is the fastest lead-off latency in high-volume DRAMs available today." In various benchmarking suites, performance improvement is readily seen when converting from PC133 3-3-3 to PC133 2-2-2 SDRAMs. WinStone 99 shows a 1 to 2 percent improvement, SiSoft Sandra shows a 10 to 20 percent improvement, and 3DMark 2000 shows a 3 to 6.5 percent improvement. Micron is the first DRAM manufacturer to meet the Intel 133MHz SDRAM device specification target goal of 2-2-2. The 2-2-2 reference refers to the following timing specifications, in clock cycles: CAS latency (CL), which is the time from read command to data out; RAS to CAS delay (tRCD), which is the time from the active command to the read command; and the RAS precharge (tRP), which is the time from precharge command to active command. 133MHz SDRAM parts meeting the 2-2-2 specification provide data faster than parts meeting the 3-3-3 specification, which is the slowest option supported by the Intel 133MHz SDRAM device specification. Because this is a new speed grade of Micron's high-volume 133MHz SDRAM, pricing for the 133MHz 2-2-2 SDRAM will be comparable to existing 133MHz product. Both registered and unbuffered DIMM modules are available for sampling in configurations ranging from 32MB to 512MB densities.

Micron Technology, Inc., and its subsidiaries manufacture and market DRAMs, SRAMs, Flash, other semiconductor components, memory modules, and personal computer systems. Micron's common stock is traded on the New York Stock Exchange (NYSE) under the symbol MU.
