概要
説明
The 71V65903 3.3V CMOS SRAM is organized as 512K x 18. It 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 71V65903 contain address, data-in and control signal registers. In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.
特長
