Abstract
A memory array circuit including a plurality of non-volatile memory cells adapted to selectively store data in either single bit mode or a multi-bit mode, control circuitry for causing control information data to be stored in first preselected ones of the plurality of cells and other data to be stored in other preselected ones of the plurality of cells, and circuitry for accessing the plurality of cells to read, program and erase the cells, the accessing circuitry functioning to access cells for storing control information data in single bit mode and cells for storing other data in either single bit or multi-bit mode.
