Abstract
A memory device that includes a memory array having pluralities of non-volatile memory cells, a plurality of index memory cells each associated with a different one of the pluralities of the non-volatile memory cells, and a controller. The controller is configured to erase the pluralities of non-volatile memory cells, set each of the index memory cells to a first state, and program first data into the memory array by reading the plurality of index memory cells and determining that a first one of the index memory cells is in the first state, programming the first data into the plurality of the non-volatile memory cells associated with the first one of the index memory cells, and setting the first one of the index memory cells to a second state different from the first state.
