ABSTRACT:
An integrated programmable logic array formed within a single silicon chip comprises a combination of an NAND or AND gate array and an NOR or OR gate array.
The NAND or AND gate array includes a plurality of bipolar transistors which are driven to operate in the forward direction by a plurality of input signals, and a plurality of Schottky barrier diodes provided between the collectors of the bipolar transistors and output signal lines. The NOR or OR gate array includes a plurality of other bipolar transistors which are driven to operate in the backward direction by a plurality of output signals from the NAND or AND gate array.
