The IDT70824 is a high-speed 4K x 16-Bit Sequential Access Random
Access Memory (SARAM). The SARAMoffers a single-chip solution to
buffer data sequentially on one port, and be accessed randomy (asyn-
chronously) through the other port. The device has a Dual-Port RAM
based architecture with a standard SRAMinterface for the random
(asynchronous) access port, and a clocked interface with counter se-
