  • Publication number: 20220335986
    Abstract: A method of operating a memory device is provided. A clock signal is received. Each clock cycle of the clock signal initiates a write operation or a read operation in a memory device. A power nap period is then determined. The power nap period is compared with a clock cycle period to determine that the power nap period is less that the clock cycle period of the clock signal. A header control signal is generated in response to determining that the power nap period is less than the clock cycle period. The header control signal turns off a header of a component of the memory device.
