In an electronic device with a serial ATA interface, upon detection of the issue or reception of a preset command, a confirmation device, such as a CPU, confirms the completion of execution of the command. Upon confirming the completion of execution of the command, a controller, which may also be the CPU, controls shifting of the serial ATA interface to a power saving mode.

According to one embodiment, a non-volatile semiconductor storage apparatus is configured to decide determination periods respectively corresponding to each of management blocks based on rewrite count information items and a temperature, and to perform a determination processing for each of management blocks for each determination period. The determination processing includes determining whether first data read from a block in the blocks is normal based on the number of errors that are occurred in the first data. The apparatus is configured to perform a rewrite processing of rewriting the first data to second data which is error-corrected when it is determined that the first data is not normal.

An electronic device has a serial ATA interface and an inhibition-signal generator. The serial ATA interface transmits data to another electronic device with a serial ATA interface connected thereto via a bus. The inhibition-signal generator is configured to generate an inhibition signal to inhibit at least one of a restoration request and a power saving request. The restoration request has the function of requesting the other electronic device to restore its serial ATA interface from a power-saving state to the non power-saving state. The power saving request is supplied from the other electronic device to the electronic device for requesting the serial ATA interface of the electronic device to shift to a power-saving state from a non power saving state.
