Abstract
A first-in/first-out (FIFO) buffer includes at least one latch-based FIFO storage line, an input flip-flop stage upstream of the at least one latch-based storage line, an output flip-flop stage downstream of the at least one latch-based storage line. The output flip-flop stage functions as an additional storage line. Clock-gating circuitry separate from the device clock controls timing of the at least one latch-based FIFO storage line, the input flip-flop stage, and the output flip-flop stage. The input flip-flop stage functions as a second additional storage line, or as an input sampling stage. Optional bypass circuitry between the input flip-flop stage and the output flip-flop stage passes data for a storage line directly to the output flip-flop stage, without passing through the at least one latch-based storage line, when the buffer is empty.
