摘要： A memory device includes a memory array, a switch device, and a controller. The switch device is arranged between a first voltage node and a second voltage node. The second voltage node is connected to the memory array. The controller is enabled to output a refresh mode signal, a refresh trigger signal, and a pre-start up signal. The memory device enters a self-refresh mode in response to the refresh mode signal. The memory device performs a self-refresh on the memory array in the self-refresh mode. In self-refresh mode, the controller outputs the pre-start up signal first prior to the refresh trigger signal to enable the switch device, so that the voltage of the second voltage node is increased to the voltage of the first voltage mode.
