Memory on-demand, managing power in memory

摘要

A memory controller for managing data and power in a memory is described. In some implementations, the memory controller is configured to identify a first area of the memory to be operated at a first power level, identify a second area of the memory to be operated at a second power level, transfer data in a region in the second area to a region in the first area, maintain a mapping of an address associated with the region in the second area to an address associated with the region in the first area, operate the first area at the first power level, and operate the second area at the second power level.

主权项

1. A method, comprising:
identifying a first area of a memory to be operated at a first power level; identifying a second area of the memory to be operated at a second power level, the first power level being higher than the second power level; transferring data in a region in the second area to a region in the first area, the region in the second area being a region that is frequently accessed by a processing device; maintaining a mapping of an address associated with the region in the second area to an address associated with the region in the first area; operating the first area at the first power level; and operating the second area at the second power level.
