The chronous, high-performance CMOS static random access memory (SRAM) devices. These SRAMs have separate I/Os, eliminating the need for high-speed bus turnaround. The rising edge of K clock initi- ates the read/write operation, and all internal operations are self-timed. Refer to the description of the basic operations of these.
