摘要：
This invention is a power conserving method and apparatus for managing a computer memory. A first memory bank comprises normal RAM. A second memory bank comprises low-power RAM. More frequently used virtual pages are mapped onto the first memory bank while less frequently used virtual pages are mapped onto the second memory bank. Further power savings are achieved by removing power from the driver circuits of the memory controller for the second memory bank when the second memory bank is not being referenced.
