Abstract: A memory device is provided, including a memory array, a driver circuit, and recover circuit. The memory array includes multiple memory cells. Each memory cell is coupled to a control line, a data line, and a source line and, during a normal operation, is configured to receive first and second voltage signals. The driver circuit is configured to output at least one of the first voltage signal or the second voltage signal to the memory cells. The recover circuit is configured to output, during a recover operation, a third voltage signal, through the driver circuit to at least one of the memory cells. The third voltage signal is configured to have a first voltage level that is higher than a highest level of the first voltage signal or the second voltage signal, or lower than a lowest level of the first voltage signal or the second voltage signal.
