Abstract
The present invention provides a storage device. The storage device includes a reset signal terminal, a clock signal terminal, a non-volatile memory, and a pull down resistance. The reset signal terminal is electrically connected to external equipment at a contact point, for receiving a reset signal. The clock signal terminal is electrically connected to the external equipment at a contact point, for receiving a clock signal. The data signal terminal is electrically connected to the external equipment at a contact point, for sending and receiving a data signal. The pull down resistance is connected to a lower side of electric potentials used by the storage device, at one terminal of the pull down resistance. The controller is initialized in response to the reset signal. The controller also writes to and reads from the non-volatile memory according to the clock signals and the data signals. The data signal includes a signal configured to raise a voltage of the data signal terminal to a higher side of the electric potentials, for instructing to write to the non-volatile memory. The data signal terminal is connected to the other terminal of the pull down resistance.
