Abstract
A RAM-based FIFO which provides self-timing of the data outputs in read mode. When the data output is not valid, the data output drivers are in a high-impedance condition. Therefore, FIFOs using this RAM-based architecture can readily be combined to provide a wider or deeper FIFO, without introducing any additional delay whatsoever. Small differential delays are preferably introduced in the activation of the output buffers, to avoid noise on power supply lines.
