Power supply device with reduced power consumption
A power supply used for providing a flash memory with an operating voltage has a plurality of memory blocks and a plurality of decoders corresponding to the memory blocks. Each memory block has a plurality of memory cells for storing binary data. Each decoder is used for selecting memory cells in the corresponding memory block. The power supply has at least three power sources for generating different voltages, and controls the power sources for making a voltage difference between a high voltage level and a low voltage level of the unselected decoder less than a voltage difference between a high voltage level and a low voltage level of the selected decoder.
