Abstract
A system having a non-volatile memory device has a plurality of memory cells that are organized into memory blocks. Blocks can operate in either a multiple bit per cell mode or a single bit per cell mode. A processor controls the system and selects blocks to operate in the multiple bit per cell mode and single bit per cell mode. One dedicated memory block is capable of operating only in the single bit per cell mode. If the dedicated memory block is found to be defective, a defect-free block can be remapped to that dedicated memory block location to act only in the single bit per cell mode.
