Random Access Port  
Description  
The IDT70825 is a high-speed 8K x 16-Bit Sequential Access  
Random Access Memory (SARAM). The SARAM offers a single-chip  
solution to buffer data sequentially on one port, and be accessed  
randomly (asynchronously) through the other port. The device has a  
Dual-PortRAMbasedarchitecturewithastandardSRAMinterfaceforthe  
random(asynchronous)accessport,andaclockedinterfacewithcounter  
High speed operation  
– 20ns tAA for random access port  
– 20ns tCD for sequential port  
– 25ns clock cycle time  
Architecture based on Dual-Port RAM cells
