描述
The 71V65803 3.3V CMOS SRAM, organized as 512K X 18, is designed to eliminate dead bus cycles when turning the bus around between reads and writes or writes and reads. Thus, it has been given the name ZBT™, or Zero Bus Turnaround. The 71V65803 contains data I/O, address, and control signal registers. In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.
