Patent attributes
A non-volatile memory storage device with functions of boosting supply voltage and signal level can adopt a non-volatile memory having an operating voltage higher than the supply voltage provided by the host device as a storage medium. The non-volatile memory storage device includes a supply voltage booster, a non-volatile memory storage unit and a controller. The supply voltage booster boosts the lower supply voltage provided by the host device up to the higher operating voltage of the non-volatile memory. The controller adjusts the interface signal to a proper interface signal level by cooperating with the supply voltage and the operating voltage so as to avoid the interface from damage owing to an over high signal level or avoid the non-volatile memory unit from not correctly receiving signal due to an over low signal level.
