Abstract
A semiconductor memory system having a nonvolatile memory and a controller configured to control the nonvolatile memory. The controller causes management data for page data to be inputted to a redundant area of the nonvolatile memory before the execution of a program and, when moving the page data in the nonvolatile memory to one other page, controls the reading of the page data to check the page data for errors during a program period for the one other page.
