FIELD-PROGRAMMABLE LOGIC DEVICE WITH PROGRAMMABLE FOLDBACK TO CONTROL NUMBER OF LOGIC LEVELS

摘要

Field-programmable logic device with programmable foldback to control number of logic levels. A field-programmable logic architecture is centered on a single array of programmable gates that perform either logical NAND or logical NOR operations. Foldback loops can be readily programmed through the array to enable the user to achieve different numbers of logic levels.
