摘要
In a conventional memory subsystem, a memory controller issues explicit refresh commands to a DRAM memory device to maintain integrity of the data stored in the memory device when the memory device is in an auto-refresh mode. A significant amount of power may be consumed to carry out the refresh. To address this and other issues, it is proposed to allow a partial refresh in the auto-refresh mode in which the refreshing operation may be skipped for a subset of the memory cells. Through such selective refresh skipping, the power consumed for auto-refreshes may be reduced. Operating system kernels and memory drivers may be configured to determine areas of memory for which the refreshing operation can be skipped.
