Abstract

In an integrated matrix of nonvolatile, reprogrammable storage cells, additional memory is provided to replace defective rows of storage cells. The addresses of the defective rows are stored in a region of the matrix. A correction register can be loaded with the addresses of the defective rows from the region of the matrix when power is first applied to the matrix or whenever the applied power deviates from the expected, nominal value.
