Abstract
A FIFO storage structure is provided with a RAM array including a number of memory locations, and control circuitry coupled to the RAM array. The control circuitry facilitates sequential write and read accesses of the memory locations, as well as non-sequential re-read of previously read memory locations. The control circuitry includes in particular circuit elements for facilitating variably deferred release and reclaiming of sequentially read in-use ones of the memory locations, thereby allowing the non-sequential re-reads to be performed in addition to the fundamentally sequential writes and reads. In each of a number of applications, a look up engine is provided with the enhanced FIFO. In one particular application, a forwarding section of a networking device is provided with such look up engine.
