A memory device includes a power supply device, a power-on-reset device, a memory array, and a memory controller. The power supply device converts the external supply voltage into an internal supply voltage. When the external supply voltage exceeds a first threshold, the power-on-reset device generates a reset signal. The power-on-reset device further raises the first threshold to a second threshold according to a deep-sleep signal. The memory array is supplied with the internal supply voltage. The memory controller is supplied with the internal supply voltage, accesses the memory array, and is reset according to the reset signal. When the memory controller operates in a deep-sleep mode, the memory controller generates the deep-sleep mode.
