Abstract
An electrically programmable memory device is proposed including: a matrix of memory cells arranged in a plurality of memory arrays and at least one redundancy array; and a substituting structure that substitutes the use of each memory array with the use of one of the at least one redundancy array in response to a failure of the memory array, wherein the memory arrays are grouped into at least one set. The substituting structure includes: a structure for associating each set with a predetermined one of the at least one redundancy array; a flag for each memory array indicative of the failure of the memory array; and a selecting for enabling each memory array or the associated redundancy array according to the corresponding flag.
