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.
Claims9
A memory module comprising:
- a power source configured to provide a first power and a second power, each at a different voltage level;
- a power controller circuit configured to generate a first memory power from the first power, to generate a second memory power from the second power, and to change the first memory power based on temperature information;
- a memory device configured to operate by being supplied with the first memory power and the second memory power;
- and
- a temperature sensor configured to generate the temperature information of the memory device,
- wherein the power controller circuit is configured to supply the first memory power having substantially the same level as the first power and to supply the second memory power having substantially the same level as the second power, when a temperature of the memory device is a first temperature.
