1. A programmable logic array device comprising:

  • means forming a first programmable AND array having a plurality of memory cells arranged in addressable rows and columns and which can be individually programmed to contain logic data;

    first input circuit means for receiving a first input signal and for developing a first buffered signal corresponding thereto;

    first row driver means responsive to said first bufferred signal and operative to interrogate a particular row of said memory cells and to cause said first AND array to output signals corresponding to the data contained therein;

    first sensing means for sensing the signals output by said first AND array and for developing a corresponding first data signal which is the logicial OR of the signals output by said first AND array;

    first signal storage means for receiving and temporily storing said first data signal;

    first output terminal means; and

    first switching means responsive to a control signal and operative to couple either said first data signal or a data signal temporarily stored in said first signal storage means to said first output terminal means.
