Abstract

See full text

In a three-dimensional nonvolatile memory, physical levels in blocks are zoned and different zones store different numbers of bits per cell so that different blocks have different data capacities. Block data capacities are calculated and recorded, and may be updated as data capacities change. User data is mapped to blocks according to their respective data capacities.
