DESCRIPTION:

CMOS Bidirectional SyncFIFO (clocked) memory which supports clock fre-

quencies up to 83MHz and have read access times as fast as 8ns. Two

independent 256/512/1,024 x 36 dual-port SRAM FIFOs on board each chip

buffer data in opposite directions. Communication between each port may

bypass the FIFOs via two 36-bit mailbox registers. Each mailbox register has

a flag to signal when new mail has been stored.

employs a synchronous interface. All data transfers through a port are gated

to the LOW-to-HIGH transition of a port clock by enable signals. The clocks for
