DESCRIPTION:
IDT72021/031/041s are high-speed, low-power, dual-port memory devices commonly known as FIFOs (First-In/FirstOut). Data can be written into and read from the memory at independent rates. The order of information stored and extracted does not change, but the rate of data entering the FIFO might be different than the rate leaving the FIFO. Unlike a Static RAM, no address information is required because the read and write pointers advance sequentially. The IDT72021/ 031/041s can perform asynchronous...
