Kind Code:
A1
Abstract:
The present invention suppresses memory cell degradation in nonvolatile memory. A memory controller is provided with a timer unit, elapsed time determination unit, and reading unit. The timer unit times the elapsed time that has passed since a prescribed time relating to an address to which data has been written. The elapsed time determination unit determines whether the elapsed time exceeds a fixed time period when the reading of data from the address is commanded. If a determination is made that the elapsed time does not exceed the fixed time period, the reading control unit pauses the reading of data from the address.
