Abstract
A nonvolatile memory apparatus is provided with a nonvolatile memory including a plurality of blocks each being a recording area of the data and a unit of erasing of the data, and a controller for controlling writing or reading of the data to/from the nonvolatile memory. Each of the blocks includes pages each being a unit of reading of the data. The controller, when data of a first page is read in response to the data read request from the external apparatus, reads data of an other page other than the first page in a block from which the data is read, and calculates a number of errors of the data in the other page, and rewrites the data into an other block when the block from which the data is read satisfies a predetermined condition on the error based on the calculated number of errors.
