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 512/1,024/2,048 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 ac-
cessed again. The FIFO has flags to indicate empty and full conditions and
two programmable flags (Almost-Full and Almost-Empty) to indicate when a
selected number of words is stored in memory. Communication between
each port may take place with two 36-bit mailbox registers. Each mailbox
