Apparatus and method for shorting retransmit recovery times utilizing cache memory in high speed FIFO

摘要

A memory circuit that allows for short retransmit recovery times by implementing a read cache memory in a FIFO device. A circuit comprising a memory array, a cache memory and a logic circuit. The memory array includes a read pointer, a write pointer and a plurality of memory rows. The cache memory is configured to store one or more memory data bits. The logic circuit is further configured to control the output of the circuit by presenting either (i) an output from the memory array or (ii) an output from the cache memory.
