Cypress Announces Production of the Industry's Highest-Density True Dual-Port Communications RAM.Business/Technology Editors 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)--April 9, 2002 World's Largest True Dual-Port Device Addresses Density and Bandwidth Requirements Bandwidth requirements (communications) The channel bandwidths needed to transmit various types of signals, using various processing schemes. Every signal observed in practice can be expressed as a sum (discrete or over a frequency continuum) of sinusoidal Of High-Performance Wireless Basestations, Storage Networks, and Communications Networks Cypress Semiconductor Cypress Semiconductor is a semiconductor design and manufacturing company. It began operations in 1982 and listed publicly in 1986. Two years later, the company shifted over to the New York Stock Exchange under the symbol, (NYSE: CY). (NYSE NYSE See: New York Stock Exchange : CY) today announced production of its 9Mb Dual-Port RAM (CY7C0853V), the world's highest density true dual-port memory. The CY7C0853V is the latest addition to Cypress's broad portfolio of high-density dual-ports including the 4Mb, 2Mb and 1Mb devices currently in production. Cypress's true dual-port memories are specifically designed to address the memory buffering requirements of high-performance wireless basestations, storage networks and wide-area networks Wide-area networks Communication networks that are regional, nationwide, or worldwide in geographic area, with a minimum distance typical of that between major metropolitan areas. Smaller networks include metropolitan and local-area networks. . The CY7C0853V provides 9Mb of synchronous, pipelined dual-ported memory capable of buffering large packets of data between two independent clock domains. Configured as a 256K x 36 bit wide device, it provides up to 9.6 Gbps of bandwidth and allows for easy interface to wide busses. Unlike alternative bank-switchable devices, the CY7C0853V is a true dual-port, providing simultaneous read and write access to any cell in its memory array from either of its two ports. In addition, the two ports may operate at independent clock speeds, allowing complete decoupling Decoupling The occurrence of returns on asset classes diverging from their normal pattern of correlation.

The devices are available in a 172 pin 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 at up to 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. . The 4Mb, 2Mb, and 1Mb devices are offered in the 172 BGA package, as well as TQFP See QFP. packages. "High density is critically important to support the buffering and internal queuing required by communications systems as line rates and processing speeds increase. The density and bandwidth provided by Cypress's newest dual-ports is ideally suited to wireless basestations and storage networks," said Christopher Norris Christopher Norris may refer to:
In many wireless infrastructure applications, multi-port memories are used to both store and manipulate packet data between baseband processing and digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). system devices operating in different clock domains. Wide area and storage networks employing high-performance communications protocols (such as OC-48, Gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. , or Fibre Channel) also use high-density multi-ported memories to buffer data packets between the backplane interconnect and the data port to avoid loss of data and maintain efficient flow control. The size of the buffer is typically driven by the difference between the input and output clocking speeds, the buffering time required by the system, and the bus width. These requirements dictate the need for a high density multi-port memory in communication systems as system speeds continue to increase. The multi-port memory may also be used in conjunction with a high density 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. (such as Cypress's Delta39K(TM) family) which controls the data flow and partitioning of the memory. The partitioning can be done to create multiple sections or "queues" inside of the memory to alleviate common networking issues such as Head of Line Blocking and enable Quality of Service classification. The high density of the Cypress 9 Mb Dual-Port will allow system designers the most queue density capability of any true dual-port memory, while the high speed will allow them to maximize the bandwidth of their system. The 9Mb Dual-Port is the latest in a line of Cypress innovations in specialty memories to address the data buffering and interprocessor communication needs of high performance communications systems. In addition, Cypress is in full production of its 4Mb dual port family in x36 configurations at up to 150 MHz. Availability and Pricing Production quantities of all densities are available now. The 9Mb devices will be priced as low as $98 in quantities of 10K units for the 9Mb devices. ------------ -------- ------------- ----------------- Device Density Configuration Package ------------ -------- ------------- ----------------- CY7C0853V 9Mb 256K x 36 172 BGA ------------ -------- ------------- ----------------- CY7C0852V 4Mb 128K x 36 172 BGA, 176 TQFP ------------ -------- ------------- ----------------- CY7C0832V 4Mb 256K x 18 120 TQFP ------------ -------- ------------- ----------------- CY7C0851V 2Mb 64K x 36 172 BGA, 176 TQFP ------------ -------- ------------- ----------------- CY7C0831V 2Mb 128K x 18 120 TQFP ------------ -------- ------------- ----------------- CY7C09579V 1Mb 32K x 36 172 BGA, 144 TQFP ------------ -------- ------------- ----------------- CY7C09389V 1Mb 64K x 18 100 TQFP ------------ -------- ------------- ----------------- Photo A high-resolution photo of the 9Mb Dual-Port Memory can be downloaded from: http://www.cypress.com/pub/9mbdp.jpg.
