An integrated circuit includes an array of memory cells, storage circuits and a write circuit coupled to the array, and a control circuit coupled to the array and write circuit. The write circuit is operable to receive initial test data and mask data. The control circuit is operable to enable the write circuit to write the initial test data to the cells, to receive an address of one of the cells, to enable the write circuit if the addressed cell is dormant to write the mask data to the storage circuit coupled to the cell such that the storage circuit stores the mask data, and to allow reading of the cell such that if the cell is dormant, then the storage circuit provides as a read value the stored mask data, and such that if the cell is live, then the storage circuit provides as the read value data that is stored in the cell.
