DESCRIPTION:
The IDT723631/723641/723651 is a monolithic high-
speed, low-power, CMOS clocked FIFO memory. It supports
clock frequencies up to 67 MHz and has read access times as
fast as 12ns. The 512/1024/2048 x 36 dual-port SRAM FIFO
buffers data from port A to Port B. The FIFO memory has
retransmit capability, which allows previously read data to be
accessed again. The FIFO has flags to indicate empty and full
conditions and two programmable flags (almost full and al-
most empty) to indicate when a selected number of words is
