Abstract
According to one embodiment, a temperature of a non-volatile memory or an ambient temperature of the non-volatile memory is acquired. A distribution of a threshold voltage, which is corrected according to the acquired temperature, is acquired from the non-volatile memory. Read voltages related to the reading of data are detected from the distribution. Error correction is performed for data read from the non-volatile memory, using the read voltages. The detected read voltages are separately corrected on the basis of the acquired temperature when the error correction has failed.
