Abstract
A memory device for repairing a neighborhood of rows in a memory array using a patch table is disclosed. In one embodiment, circuitry in the memory device is operative to store, in a temporary storage area of the memory device, (i) first data to be stored in row N in the memory array, (ii) second data, if any, stored in row N−1 in the memory array, and (iii) third data, if any, stored in row N+1 in the memory array. The circuitry is operative to write the first data in row N in the memory array, and, in response to an error in writing the first data, to write the first data, the second data, if any, and the third data, if any, in respective rows in a repair area in the memory device. The circuitry is further operative to add the addresses of rows N−1, N, and N+1 to a table stored in the memory device.
