Abstract: A device for managing compressible computer memory is described. The device has a memory region categorization arrangement configured to monitor memory requests to the computer memory and categorize memory regions based on spatio-temporal locality of the memory requests made to the memory regions. A memory region is categorized to exhibit low spatio-temporal locality when memory requests to said memory region are less frequent than a threshold. The device further has a selective computer memory management arrangement operatively connected with the memory region categorization arrangement and comprising a bypassed memory access mechanism and a compressed memory access mechanism. The bypassed memory access mechanism is configured to handle memory contents of memory regions categorized to exhibit low spatio-temporal locality in uncompressed form in the computer memory.

Abstract: A method for accessing compressed computer memory residing in physical computer memory is disclosed. In the method, compressed memory blocks are represented as sectors, wherein all sectors contain a fixed number of compressed memory blocks, have a fixed logical size in the form of the fixed number of compressed memory blocks, and have varying physical sizes in the form of the total size of data stored in the respective compressed memory blocks.
