GS8342Q19BGD Datasheet, GSI Technology

* 2.0 Clock Latency
* Simultaneous Read and Write SigmaQuad™ Interface
* JEDEC-standard pinout and package
* Dual Double Data Rate interface
* Byte Wr.

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