Abstract:
A method and system for extending the life span of a flash memory device. The flash memory device is dynamically configurable to store data in the single bit per cell (SBC) storage mode or the multiple bit per cell (MBC) mode. In the MBC storage mode, the cell can have one of multiple possible states, where each state is defined by respective threshold voltage ranges. In the SBC mode, the cell can have states with threshold voltages corresponding to states of the MBC storage mode which are non-adjacent to each other to improve reliability characteristics of the cell.
