Abstract: Examples relate to an approximative memory deduplication method, a controller apparatus or controller device for a memory or storage controller, a memory or storage controller, a computer system and to a computer program. The approximative memory deduplication method comprises determining a hash value of a data block. The hash value is based on a user-defined approximative hashing function. The approximative memory deduplication method comprises storing a quantized version of the data block based on the hash value using a memory or storage device of the computer system.

Abstract: Various systems and methods for computer memory management are described herein. A system for computer memory management includes a first memory device including a mapping table; a second memory device including a staging area; a third memory device including a dedup data region; and a controller operable to: receive a memory access request, the memory access request including an address and data; write the data to the staging area; and update the mapping table with the address.

Abstract: Processing circuitry for computer memory management includes memory reduction circuitry to implement a memory reduction technique; and reference count information collection circuitry to: access a memory region, the memory region subject to the memory reduction technique; obtain an indication of memory reduction of the memory region; calculate metrics based on the indication of memory reduction of cache lines associated with the memory region; and provide the metrics to a system software component for use in memory management mechanisms.

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.

Abstract: Various systems and methods for computer memory management are described herein. A system includes a memory controller to: monitor utilization of a memory device, the memory device used with a memory compression technique; determine that the utilization of the memory device violates a threshold; and initiate a system interrupt to provoke a response, responsive to the utilization of the memory device violating the threshold.
