<p>A propagating first-in, first-out (FIFO) storage device is driven by a two-phase non-overlapping clock and includes a plurality of storage cells (C1, ...C4) and a plurality of tracking bit cell circuits (T1, ...T4). Each of the storage cells includes first pass gate transistors (G1, ...G8), first inverters (INV1, ...INV8), second pass gate transistors (G9, ...G16), and second inverters (INV9, ...INV16). The first pass gate transistors are responsive to a control signal from the tracking circuit for loading data input signals into the first inverter means. The second pass gate transistors are responsive to a first phase of the clock for shifting the data input signals into the second inverters.</p> |
