  • Synchronous FIFO having an alterable buffer store
    Patent number: 5406554
    Abstract: A synchronous first-in, first-out ("FIFO") having an alterable buffer store includes a dual-ported, random access memory ("RAM") based memory device incorporating conventional "empty" and "full" flags while also providing an alternate mode of operation in which the inhibiting effects of the "empty" and "full" flags are disabled whereby information contained within the FIFO may be modified before being read out. The alternate mode of operation is particularly useful in asynchronous transfer mode ("ATM") networking applications.
