Abstract

In a nonvolatile memory system that includes a block-erasable memory array, records are individually maintained for certain classifications of blocks. One or more lists may be maintained for the blocks, an individual list ordered according to a descriptor value. Such ordered lists allow rapid identification of a block by descriptor value.
