Abstract: A buffer/interface device of the memory node may read and compress blocks of data (e.g., pages). When a memory buffer device compresses a block of data, it may keep storing the original uncompressed version in the original memory location (e.g., physical memory page). In this manner, an access directed to the block of data may be satisfied with the uncompressed version retrieved from the original memory location (e.g., physical memory page) without having to perform a decompression operation. As memory space is needed for other purposes (e.g., for an uncompressed copy of a recently decompressed block or as host allocated memory occupies more space), the original uncompressed versions of blocks (pages) that have not been accessed relatively recently (e.g., relative to other kept original uncompressed versions) may be evicted and replaced by other blocks of data (e.g., either compressed or uncompressed).
