1. Apparatus for storing data and for providing data serially at high data rates, said apparatus comprising:

  • (a) means for storing data at a plurality of memory locations;

    (b) means, responsive to a first enabling signal, for sensing data stored by said storing means, said sensing means provided sensed data;

    (c) means, responsive to a second enabling signal, for selectively coupling a memory location of said storing means to said sensing means to permit the sensing of the data stored thereby;

    (d) means, responsive to a third enabling signal, for latching said sensed data, said latching means being coupled to said sensing means;

    (e) means, responsive to a fourth enabling signal, for generating an address signal identifying a memory location of said storing means, said generating means providing said address signal to said selectively coupling means; and

    (f) control means for providing said first, second, third and fourth enabling signals, said control means providing said first, second, third and fourth enabling signals such that;

    (i) said generating means generates a first predetermined address signal while said selectively coupling means couples said sensing means to sense the data at a memory location corresponding to a second predetermined address signal, said second predetermined address signal having been generated prior to said first predetermined address signal, and said latching means receives the sensed data corresponding to said second predetermined address signal; and

    (ii) said latching means latches said sensed data corresponding to said second predetermined address signal at least until said selectively coupling means receives said first predetermined address signal and couples said sensing means to the memory location corresponding to said first predetermined address signal.
