Abstract
In one embodiment, aggregated write back in a direct mapped two level memory in accordance with the present description, aggregates a dirty block or other subunit of data being evicted from a near memory of a two level memory system, with other spatially co-located dirty subunits of data in a sector or other unit of data for write back to a far memory of the two level memory system. In one embodiment, dirty spatially co-located subunits are scrubbed and aggregated with one or more spatially co-located dirty subunits being evicted. In one embodiment, a write combining buffer is utilized to aggregate spatially co-located dirty subunits prior to being transferred to a far memory write buffer in a write back operation. Other aspects are described herein.
