Patent ID: 8514654

Claim:
A storage apparatus comprising: a plurality of terminals including a reset terminal, a clock terminal, a power supply terminal and a ground terminal, the reset terminal being configured to be connected to a host side reset terminal to which a reset signal is supplied from a host device, the clock terminal being configured to be connected to a host side clock terminal to which a system clock is supplied from the host device, the power supply terminal being configured to be connected to a host side power supply terminal to which a power supply voltage is supplied from the host device, the ground terminal being configured to be connected to a host side ground terminal to which ground voltage is supplied from the host device; a nonvolatile storage section, and a control section that controls the nonvolatile storage section, wherein the control section comprises: a detection circuit that detects a floating state in at least one of the power supply terminal and the ground terminal, the detection circuit being configured to output a detection signal indicating whether the floating state is detected or not; and a mask process circuit that performs a mask process of a system clock that is used to control the nonvolatile storage section, wherein the mask process circuit inputs the detection signal, and masks the system clock when the floating state is detected by the detection circuit.
