    摘要: The present invention provides a memory device including a memory array, an IO circuitry and a control circuit. The IO circuitry includes a write buffer and a negative voltage provider. The write driver is configured to receive input data to drive bit lines of the memory array, and the negative voltage provider is configured to generate to generate a negative voltage to the write driver. The control circuit includes an NBL timing control circuit configured to generate an NBL enable signal to selectively enable the negative voltage provider. In addition, the memory device is supplied by a first supply voltage and a second supply voltage, a voltage level of the second supply voltage is higher than a voltage level of the first supply voltage, and the negative voltage provider and the NBL timing control circuit are supplied by the second supply voltage.
