Abstract: Various systems and methods for computer memory overcommitment management are described herein. A system for computer memory management includes a memory device to store data and a mapping table; and a memory overcommitment circuitry to: receive a signal to move data in a first block from a memory reduction area in the memory device to a non-memory reduction area in the memory device, the memory reduction area to store data using a memory reduction technique, and the non-memory reduction area to store data without any memory reduction techniques; allocate a second block in the non-memory reduction area; copy the data in the first block to the second block; and update the mapping table to revise a pointer to point to the second block, the mapping table used to store pointers to memory device in the memory reduction area and the non-memory reduction area.
