Abstract
A method and an apparatus are provided for powering off a portion of a memory of a mobile system. The apparatus may store data within a memory of the apparatus. The apparatus may copy a first portion of the data stored in a first portion of the memory into a second portion of the memory so that the data is stored in the second portion of the memory. The first and the second portion of the memory may be the same memory type. The disclosure discusses various triggering events that may cause the apparatus to copy the first portion of the data stored in the first portion of the memory into the second portion of the memory. The apparatus may then turn off the first portion of the memory. In this manner, the memory consumes less power when storing the data during a low power mode.
