Hitachi Provides SDRAM Components, Modules and Clock Drivers for Industry's Comprehensive PC133 Solution.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--March 1, 1999 -- Low-Cost, High-Performance Main Memory Option to Provide Evolutionary Step between PC100 and Double Data Rate 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. Hitachi Semiconductor (America) Inc. today announced the availability of a complete array of Synchronous DRAM Synchronous DRAM - Synchronous Dynamic Random Access Memory (SDRAM) main memory solutions for computer systems utilizing the new 133 MHz (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. (PC133) system bus, providing the stepping stone between PC100 and Double Data Rate (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 ) SDRAM. Leveraging state-of-the-art 0.18-micron process technology to introduce 64-Mbit PC133 SDRAM components, Hitachi will incorporate them within 64-, 128- and 256-MByte dual in-line memory modules See DIMM. (storage) Dual In-line Memory Module - Small circuit boards carrying memory integrated circuits, with signal and power pins on both sides of the board, in contrast to single-in-line memory modules (SIMM). (DIMMs) to target high-end PC, workstation and server applications. Additionally, Hitachi's 133-MHz Phase Locked Loop (PLL PLL - phase-locked loop ) clock drivers -- the industry's only such solution -- are incorporated into Hitachi's registered SDRAM modules and available separately for designs that require reliable data access and storage at 133-MHz system speeds.

PC133 provides a 33 percent performance gain for only a small incremental cost Incremental Cost The encompassing change that a company experiences within its balance sheet due to one additional unit of production. Notes: Incremental cost is the overall change that a company experiences by producing one additional unit of good. since it is an evolutionary step from the widely deployed PC100 bus architecture. PC133 SDRAM helps facilitate this migration through the use of standard SDRAM packaging (54-pin TSOP (Thin Small Outline Package) A very thin, plastic, rectangular surface mount chip package with gull-wing pins on its two short sides. TSOPs are about a third as thick as SOJ chips. See gull-wing lead, SOP, SOJ and chip package. ) and the incorporation of the same control lines as PC100 versions. PC133 SDRAM represents a return to product standards that are defined by the DRAM manufacturers and based upon a realistic assessment of technology issues and cost infrastructure. Hitachi's introduction of PC133 solutions gives the market a single, end-to-end source for this migration as well as the necessary enabling technology to develop modules with dependable clock distribution. "The advent of sub-quarter-micron process geometries has made the progression towards PC133-capable SDRAM components inevitable," said Walter Juras, DRAM product marketing engineer at Hitachi Semiconductor (America) Inc. "From this standpoint, PC133 is a solution that makes perfect sense to the industry: an evolutionary, scaleable technology delivered at a low premium." "Semico believes that 133-MHz DRAM provides the evolutionary progression demanded by computer OEMs," said Sherry Garber, senior vice president at Semico Research Corp. "The 133-MHz SDRAM modules make sense because they can be manufactured in high volume without major investment. As such, this technology is ready for market at a reasonable price." -0-
