512 x 18 x 2 / CLOCKED BIDIRECTIONAL FIRST-IN/ FIRST-OUT MEMORY
A FIFO memory is a storage device that allows data to be written into and read from its array at independent data rates. The SN74ABT7819 is a high-speed, low-power BiCMOS bidirectional clocked FIFO memory. Two independent 512 ×18 dual-port SRAM FIFOs on the chip buffer data in opposite directions. Each FIFO has flags to indicate empty and full conditions, a half-full flag, and a programmable almost-full/almost-empty flag.
