ABSTRACT:
A programmable logic device has an architecture which permits to implement logic functions through loopable multi-levels by utilizing a network of distributed memory arrays organized as a mosaic of arrays of programmable memory cells and multifunctional interfacing blocks. Each of said blocks contains an input selection circuitry capable of receiving input signals coming from bidirectional input/output pins and/or from outputs of said arrays, signal selection means, polarity selection means and path selection means and an output sorting circuitry capable of selecting non-stored or stored type, data containing signals, selecting the polarity and the path of said signals toward enableable output drive buffers of said plurality of bidirectional input/output pins and/or toward the inputs of any one of said arrays, a circuitry capable of producing for each of said signals a first, non-inverted, and a second, inverted, buffered replica signals with which to drive the rows of one or more of said memory arrays for causing the output of signals from those arrays, each array being programmable in order to perform different logic functions for any combination of inputs thereof and the exchange between two different arrays and between an array and the external world taking place essentially through at least one of said multfunctional blocks.
