www.DataSheet4U.com 25/0251 CY7C09089/99 CY7C09189/99 64K/128K x 8/9 Synchronous Dual-Port Static RAM .
The CY7C09089/99 and CY7C09189/99 are high-speed synchronous CMOS 64K and 128K x 8/9 dual-port static RAMs.
Features
* True dual-ported memory cells which allow simultaneous access of the same memory location
* Six Flow-Through/Pipelined devices
* 64K x 8/9 organizations (CY7C09089/189)
* 128K x 8/9 organizations (CY7C09099/199)
* Three Modes
* Flow-Through
Applications
* A port’s burst counter is loaded with the port’s Address Strobe (ADS). When the port’s Count Enable (CNTEN) is asserted, the address counter will increment on each LOW-to-HIGH transition of that port’s clock signal. This will read/write one word from/into each successive address location until CNTE
