Abstract

A memory device comprises a plurality of first and second non-volatile memory cells arranged as an array. Each memory cell stores information. The memory device further comprises an access unit coupled to the array. The access unit stores information in the plurality of first and second non-volatile memory cells. The memory device further comprises a verifying unit coupled to the array. The verifying unit verifies the information stored in a group of the first and second memory cells by verifying only a subset of the group. The subset comprises at least one of the second memory cells.
