Segmented row repair for programmable logic devices

A programmable logic device comprising:

• a first row of logic array blocks comprising a first plurality of programmable elements;
• a second row of logic array blocks comprising a second plurality of programmable elements, wherein the first and second rows of logic array blocks are segmented into a first segment and a second segment that are each smaller than a row and that are separately repairable independent of other segments in the same row;
• and
• repair circuitry disposed between the first and second segments, wherein the repair circuitry remaps logic from the first row to a third row of logic array blocks within the first segment when a logic array block of the first row of logic array blocks in the first segment has failed.

A method comprising:

• determining that a first logic array block in a first segment of logic array blocks of a programmable logic device has failed, wherein the first logic array block is in a first row of the logic array blocks;
• determining that a second logic array block in a second segment of the logic array blocks has failed, wherein the second logic array block is in a second row of the logic array blocks;
• remapping, using repair circuitry, a first set of logic within the first segment, wherein the first segment is smaller than the first row and repairable independent of whether another segment of the first row is repaired;
• and
• remapping, using the repair circuitry, a second set of logic within the second segment, whether the second segment is smaller than the second row and repairable independent of whether another segment of the second row is repaired.
