Cypress 4 Mbit Dual Port Memory Provides Density Upgrade For High-End Storage Networks, High-Speed WANs and Wireless Infrastructure Applications.Business Editors & High Tech Writers SAN JOSE, Calif.--(BUSINESS WIRE)--Sept. 25, 2000 High-Density, True Dual-Port, High-Speed RAM is First to Offer Power-Saving 2.5V HSTL HSTL High-Speed Transceiver Logic (family of logic integrated circuits) HSTL High-Speed Transistor Logic (electronics) I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output , Provides Simple Upgrade from 1 Mbit Cypress Semiconductor (NYSE NYSE See: New York Stock Exchange : CY) today announced the industry's first 4 Mbit, true dual-port memory to offer a power-saving 2.5V high-speed transistor logic (HSTL) I/O, targeted at applications in high-end storage networks, high-speed wide-area networks (WANs) and wireless infrastructure applications. This 4 Mbit specialty memory simplifies its implementation by providing pin compatibility with its 1 Mbit counterpart in the 172-ball grid array (BGA (Ball Grid Array) A popular surface mount chip package that uses a grid of solder balls as its connectors. Available in plastic and ceramic varieties, BGA is noted for its compact size, high lead count and low inductance, which allows lower voltages to be used. ) package - making the device both small and highly manufacturable at a size of 15mm x 15mm with a 1.0 mm pitch - in addition to a TQFP See QFP. . The CY7C0852 is configured as a synchronous, dual-ported, 128K x 36 memory, as well as a 256K x 18, 64K x 36, and 128K x 18. It will be offered in both 2.5V HSTL and 3.3V LVTTL LVTTL Low Voltage Transistor Transistor Logic (AMCC) LVTTL Low Voltage Transistor to Transistor Logic I/O versions. The device is capable of transferring 10.8 Gigabits per second at a speed of 150 MHz, easing communications bottlenecks, enabling more efficient backplane management and increasing overall system performance. Its low-power HSTL I/O provides an easy interface to common communications ICs, CPLDs, ASICs, and processors. The device will be manufactured using Cypress's RAM7(TM), fast transistor, 0.15-micron, CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. process. "The 4 Mbit dual-port establishes the upgrade path to higher densities for designers currently using Cypress's 1 Mbit dual-port memories," said Chris Norris, Cypress's vice president, data communications division. "A growing number of designers rely on Cypress as the leader in dual-ported memories due to the technological advantages our devices offer. We delivered a 1 Mbit true dual-ported memory ahead of our competitors, and our new products will lead our customers to higher densities and bandwidths." "For our WAN customers, this 4 Mbit dual-port facilitates the prioritization of incoming voice, video and data to facilitate quality of service (QoS) and eliminate head of line (HOL) blocking issues," added Geoff Charubin, data communications division director of marketing. "Customers typically use the device to store and buffer data in conjunction with CPLDs." When integrated into storage networks, the CY7C0852V enhances data manipulation and processing by buffering data from and within fiber channel switches, RAIDs and host bus adapters (HBAs). This enables more efficient backplane management, real-time backup, and reliable data transfer. The 4 Mbit dual-port shares its target applications - high-performance switching and routing systems - with many other Cypress devices, including other specialty memories like FIFOs and data communications devices such the RoboClock(TM) and HOTLink(TM) components. Communications customers that area already familiar with or have used Cypress's quad-data-rate (QDR QDR Quadrennial Defense Review (US DoD) QDR Quad Data Rate (Memory Technology) QDR Quality Deficiency Report QDR Quality, Durability and Reliability (Toyota Motor Company) ), synchronous SRAM See static RAM. SRAM - static random-access memory , CPLD (Complex PLD) A programmable logic device that is made up of several simple PLDs (SPLDs) with a programmable switching matrix in between the logic blocks. CPLDs typically use EEPROM, flash memory or SRAM to hold the logic design interconnections. See PLD and SPLD. , and clock solutions are ideal candidates who would benefit from the 4 Mbit dual-port memory.
