GS8662S09E-200 sram equivalent, ddr sigmasio-ii sram.
* Simultaneous Read and Write SigmaSIO™ Interface
* JEDEC-standard pinout and package
* Dual Double Data Rate interface
* Byte Write controls sampled at d.
where alternating reads and writes are needed. On the other hand, Common I/O SRAMs like the SigmaCIO family are popular .
