Programmable logic device having redundancy with logic element granularity
摘要:
A PLD having logic element row granularity redundancy is disclosed. The PLD includes a plurality of LABs arranged in an array and a plurality of horizontal and vertical inter-LAB lines interconnecting the LABs of the array. Each of the LABs further includes a predetermined number of logic elements and redundancy circuitry to replace a defective logic element with a non-defective logic element among the predetermined logic elements by shifting programming data intended to for the defective logic element to the non-defective logic element.
