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. The method involves providing sector-based translation metadata to keep track of the sectors within a compressed memory page, receiving a physical memory access request comprising an address in the physical computer memory, using the address in the physical memory access request to derive a memory block index, using the memory block index and the fixed logical size of the sectors to determine a sector id, using the sector-based translation metadata to locate a sector having the sector id in the compressed memory page, and using the address of the physical memory access request to locate the requested data within said sector.
