Abstract
A storage device has a data erasing function. A controller of a storage device, such as an USB, has a lost timer section and an emergency timer section. Both timer sections halt clocking operation as a result of initiation of use of the storage device by an authorized user. The lost timer section commences clocking operation as a result of completion of use of the storage device by the authorized user. The emergency timer section commences clocking operation as a result of unauthorized removal of the storage device. When either the lost timer section or the emergency timer section outputs a count-up signal, data in flash ROM are erased.
