Abstract
A nonvolatile memory is configured with blocks as deletion units, each block having several pages that are configured as write units. A controller for the nonvolatile memory includes an error correcting circuit, which detects and corrects an error in data read out of a page in one of the blocks of the nonvolatile memory, the page being referenced by a logical address. The controller also determines an error occurrence when the error cannot be corrected. An error block table is provided to store the logical address where the error occurred, and a physical address corresponding to the logical address.
