Features
* For use with GSI FPGA-based Controller IP
* 3.0 Clock Latency
* Simultaneous Read and Write SigmaQuad™ Interface
* JEDEC-standard pinout and package
* Dual Double Data Rate interface
* Byte Write controls sampled at data-in time
* Burst of 4
Applications
* where alternating reads and writes are needed. Therefore, the SigmaQuad-II+ SRAM interface and truth table are optimized for alternating reads and writes. Separate I/O SRAMs are unpopular in applications where multiple reads or multiple writes are needed because burst read or write transfers from Se
