Abstract
The present invention provides a circuit for generating a programmable write-read word line equality signal in FIFO buffers. The present invention significantly reduces the gate delay associated in producing the write-read word line equality signal. The delay is reduced from a typical 30-50 gate delays, to as little as four gate delays. The present invention accomplishes this by processing several bit operations in parallel and making the general circuit architecture symmetric. The delay is constant in all of the parallel paths but amounts to only a short delay for the final WREQ output.
