Abstract
A memory includes a memory cell including a memory transistor in which electric charges are stored in an electric charge storage layer when data is written to the memory cell, and a controller configured to control a voltage to be applied to the memory transistor in a predetermined hold time until an amount of electric charges stored in the electric charge storage layer decreases to an amount of electric charges corresponding to a state where the data is erased from the memory cell.
