Basic logic cell for programmable logic device combining two data signals according to logic function selectable by numerous logic selection elements, with four data signal inputs for two data signals, their complementary data signals

摘要

A basic logic cell comprises four data signal inputs for two data signals and their logical complement signals, and four logic selection elements between inputs. Logical combinations of two data signals are available at the data signal output according to a logic function that is selected by logic selection elements. Preferably the logic selection element are of unalterable hardware type, e.g. formed by several metalized levels and or vias and are in the form of specified transistors. Independent claims are included for a basic logic cell appliance and logic module.
