Abstract: Technology for managing non-volatile memory. A bitmap may be maintained in NAND memory cells. The bits in the bitmap map to an address (e.g., PBA) in the NAND memory cells. Each bit has either a first value to indicate that the corresponding address stores valid data or a second value to indicate that the corresponding address does not store value data. Garbage collection may be performed based on the bitmap. Bit-level memory operations are performed to maintain the bitmap. Bit-level erase may be performed to erase a memory cell to have a value that indicates a valid/invalid status. The bitmap may contain unencoded data. In one aspect, a one's complement to the bitmap is stored in the NAND memory cells. The one's complement has opposite values as the regular bitmap. The system may compare the values in the regular bitmap and the one's complement bitmap for data integrity.
