MEMORY POWER MANAGEMENT AND DATA CONSOLIDATION

摘要

According to embodiments of the disclosure, methods, systems and computer program products for memory power management and data consolidation are disclosed. The method may include selecting a first real memory portion and a second real memory portion from a plurality of real memory portions coupled to a memory controller in a computer system by a memory bus. The first real memory portion may be connected to a first buffer and the second real memory portion may be connected to a second buffer. The first and second real memory portions may be selected by the memory controller. The method may include migrating data from the first real memory portion to the second real memory portion on a migration bus through the first and second buffers. The method may also include placing the first real memory portion into a reduced power mode.
