Abstract
A storage apparatus including a nonvolatile storage section and a control section controlling the nonvolatile storage section, wherein the control section has a detection circuit detecting floating state in at least one of power supply terminal connected to host side power supply terminal to which a power supply voltage is supplied from the host device, and ground terminal connected to host side ground terminal to which a ground voltage is supplied from the host device and a mask process section performing a mask process of the system clock that is used to control the nonvolatile storage section, wherein the mask process section masks the system clock if the floating state is detected by the detection circuit.
