Nonvolatile storage apparatus

A nonvolatile storage apparatus, comprising a first semiconductor device and a second semiconductor device controlled by the first semiconductor device,

• wherein the first semiconductor device, upon detecting that an operating supply voltage supplied from outside has reached or exceeded a prescribed voltage, responds to an initialization command supplied from outside and starts reset exception processing,
• wherein, after the reset exception processing is completed, the first semiconductor device does not respond to the initialization command, and
• wherein, when a prescribed amount of time has elapsed after the reset exception processing was started, the first semiconductor device again responds to the initialization command and starts the reset exception processing.

A nonvolatile storage apparatus, comprising a first semiconductor device and a second semiconductor device controlled by the first semiconductor device,

• wherein the first semiconductor device, upon detecting that an operating supply voltage supplied from outside has reached or exceeded a prescribed voltage, responds to an initialization command supplied from outside and starts reset exception processing,
• wherein, after the reset exception processing is completed, the first semiconductor device does not respond to the initialization command, and
• wherein, when a read access error is detected in making a read access to a memory storing a program for the reset exception processing before the reset exception processing is completed, the first semiconductor device again responds to the initialization command and starts the reset exception processing.

A nonvolatile storage apparatus, comprising a first semiconductor device having a data processing section and a second semiconductor device controlled by the first semiconductor device,

• wherein the first semiconductor device, upon detecting that an operating supply voltage supplied from outside is not lower than a prescribed voltage, responds to an initialization command supplied from outside and starts reset exception processing by the data processing section,
• wherein, after the reset exception processing is completed, the first semiconductor device does not respond to the initialization command, and
• wherein, when a state in which the data processing section has become or is anticipated to become out of control is reached during the reset exception processing, the first semiconductor device again responds to the initialization command and starts the reset exception processing by the data processing section.

A semiconductor device, comprising a data processing section capable of executing instructions and an external interface section, the semiconductor device being formed over a semiconductor substrate,

• wherein the semiconductor device, upon detecting that an operating supply voltage supplied from outside has reached or exceeded a prescribed voltage, responds to an initialization command supplied from outside and starts reset exception processing by the data processing section,
• wherein, after the reset exception processing is completed, the semiconductor device does not respond to the initialization command, and
• wherein, when the reset exception processing has not been completed with a prescribed amount of time having elapsed after the reset exception processing was started, the semiconductor device again responds to the initialization command and starts the reset exception processing by the data processing section.
