Abstract
A buffer/interface device of a memory node reads a block of data (e.g., page). As each unit of data (e.g., cache line sized) of the block is read, it is compared against one or more predefined patterns (e.g., all 0's, all 1's, etc.). If the block (page) is only storing one of the predefined patterns, a flag in the page table entry for the block is set to indicate the block is only storing one of the predefined patterns. The physical memory the block was occupying may then be deallocated so other data may be stored using those physical memory addresses.
