Abstract
A memory module may include a power source, a memory device, and a power controller. The power source provides at least one power supply voltage. The memory device operates by being supplied with at least one memory power supply voltage. The power controller supplies the at least one memory power supply voltage by changing a voltage level of the at least one power supply voltage based on operation modes of the memory device.
Claims25
A memory module comprising:
- a memory device configured to operate by being applied with a first memory power supply voltage, and configured to perform a refresh operation when a refresh signal is received;
- a voltage gating circuit configured to provide a first power supply voltage supplied from a power source, as the first memory power supply voltage, when a gating signal is an enabled state;
- a voltage sensing circuit configured to generate a sensing signal when a level of the first memory power supply voltage is greater than or equal to a predetermined level;
- and
- a power control circuit configured to generate the gating signal based on a command signal, and generate the refresh signal based on the command signal and the sensing signal.
