Patent ID: 7317632

Claim:
A non-volatile memory storage device, comprising: a supply voltage booster for receiving an external voltage, boosting that voltage and then outputting an internal voltage at a voltage level greater than the external voltage; a non-volatile memory storage unit coupled to the supply voltage booster for receiving the internal voltage; and a controller coupled to the non-volatile memory storage unit and being coupled to the supply voltage booster for receiving the internal voltage, the controller including: a non-volatile memory interface unit for transferring digital information signals between the non-volatile memory storage unit and the controller at a voltage level boosted to conform to the internal voltage, the non-volatile memory interface unit being electrically connected to the non-volatile memory storage unit and receiving the internal voltage; and a host device interface unit for transferring digital information signals between a host device and the non-volatile memory interface unit at a voltage level conforming to the external voltage, the host device interface unit being coupled to the host device and the non-volatile memory interface unit and receiving the external voltage.
