IDT723631 - 512 x 36  
IDT723641 - 1,024 x 36  
IDT723651 - 2,048 x 36

Fast access times of 11ns  
DESCRIPTION:  
Free-running CLKA and CLKB can be asynchronous or coinci-  
dent (permits simultaneous reading and writing of data on a  
single clock edge)  
Clocked FIFO buffering data from Port A to Port B  
Synchronous read retransmit capability  
Mailbox register in each direction  
Programmable Almost-Full and Almost-Empty flags  
Microprocessor interface control logic  
Input Ready (IR) and Almost-Full (AF) flags synchronized by  
CLKA  
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
