Abstract
Power consumption for refresh of memory devices on a memory module is reduced by each memory device on the memory module to one of a plurality of sub channels on the memory module. Each sub channel has a thermal sensor that monitors the temperature of the DRAM chips in the region. The refresh rate is increased only for the memory devices in the sub channel in which the memory devices operate above a predefined high temperature. This results in a reduction in power required by the memory module for refresh and an increase in the maximum bandwidth of the memory module.
