GS8342Q18E-250 Datasheet, GSI Technology

* Simultaneous Read and Write SigmaQuad™ Interface
* JEDEC-standard pinout and package
* Dual Double Data Rate interface
* Byte Write controls sampled at .

where alternating reads and writes are needed. Therefore, the SigmaQuad-II SRAM interface and truth table are optimized .
