Abstract

See full text

It is assumed that at least one of the plurality of nonvolatile semiconductor memory devices is a nonvolatile semiconductor memory device (hereinafter, referred to as a first memory device) in a low power consumption state in which error check processing and refresh processing cannot be performed. A storage apparatus releases a low power consumption state of a first memory device at a timing according to a lapsed time after the first memory device is in the low power consumption state and an estimated ambient temperature of the first memory device at the lapsed time. When the low power consumption state is released, the first memory device executes the error check processing and the refresh processing.
