Abstract
A method for controlling a semiconductor storage device including memory cells each configured to hold data of 2 bits or more, the method includes starting first signal processing, and inputting lower bits into the semiconductor storage device in a ready state, writing the lower bits to the memory cells, changing the semiconductor storage device from the ready state into a busy state, changing the semiconductor storage device from the busy state into the ready state, and finishing the first signal processing, starting second signal processing, and inputting upper bits into the semiconductor storage device in the ready state, and writing the upper bits to the memory cells. A period for the writing the upper bits is longer than a period for the writing the lower bits. A period for performing the second signal processing is longer than a period for performing the first signal processing.
