Abstract:
1. An apparatus comprising: a Dual In-line Memory Module (DIMM) comprising a plurality of Dynamic Random Access Memory (DRAM) units to store data, wherein each DRAM unit includes a plurality of banks and each bank is divided into a plurality of sub-banks; and a memory management unit to allocate a set of interleaved sub-banks of said DIMM to a memory page of an Operating System, wherein a combined memory size of the set of interleaved sub-banks is equal to a size of the memory page of the Operating System, wherein the Operating System is to create a memory page corresponding to the allocated set of interleaved sub-banks and wherein the Operating System is to create a page table associated with an indication as to whether or not the set of interleaved sub-banks has context, wherein the DRAM units are to selectively self-refresh power to the set of interleaved sub-banks if the set of interleaved sub-banks has context and to avoid self-refresh of power to the set of interleaved sub-banks if the set of interleaved sub-banks does not have context, wherein leakage power associated with avoiding self-refresh power is less than self-refresh power.
