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.
Claims6
A memory module comprising:
- a memory device configured to operate by being applied with a first memory power supply voltage;
- a voltage gating circuit configured to provide one of a first power supply voltage supplied from a power source and a low voltage, as the first memory power supply voltage, based on a gating signal, the low voltage having a lower level than the first power supply voltage;
- and
- a module controller configured to generate the gating signal based on a voltage flag, and generate a refresh signal based on a command signal and a result of sensing a level of the first memory power supply voltage.
