Cypress Reaches Volume Production of High Density 18-Mbit Dual-Port RAM

12/23/2003 - Cypress Semiconductor Corporation (NYSE: CY) announced that it has reached volume production of the world’s highest-density and highest-bandwidth dual-port (DP) RAM. The FLEx72TM 18-Mbit DP RAM is a synchronous, pipelined dual-port memory that provides 72-bit wide ports enabling up to 19.2 Gbps of bandwidth – 60 percent more than alternative devices.

The FLEx72 DP RAM provides simultaneous access to any location in the memory — either port can write and read data into and out of any memory location at the same time. This feature, combined with the ability to run both ports in two independent clock domains, enables the buffering of large packets of data between two processing elements in a system. It also eliminates bus contention issues by enabling system architects to create a distributed bus architecture.

“With its unprecedented combination of performance and storage capability, the FLEx72 DP RAM is the optimal solution for next-generation communication systems and video and image processing systems,” said Rajiv Nema, Marketing Manager for Dual Ports for Cypress’s Data Communication Division. “Cypress has consistently been first to market with the most advanced multi port memories; by doing so, our customers can get to market in shorter time with highly differentiated products.”

Configured as a 256K x 72 device, the FLEx72 DP RAM operates up to 133 MHz and provides synchronous SRAM interface to processors, DSPs, FPGAs and ASICs. Available in a 484-ball FBGA package, the FLEx72 DP RAM features low operating voltage (3.3 V) and low standby & dynamic power consumption. This device includes full range of features such as separate byte enables, master reset, mailbox interrupts for port-to-port message passing, IEEE 1149.1 compatible JTAG interface for improved manufacturability and more.

The addition of the FLEx72 18-Mbit devices expands Cypress’s broad dual-port memory portfolio, which includes the FLEx36TM family of 1-Mbit, 2-Mbit, 4-Mbit and 9-Mbit devices currently in production. For more information on Cypress’s portfolio of dual-port memories visit the Cypress website at:
