Claim 1:
2. The device for accessing compressed computer memory as defined in claim 1, wherein the decompressor is configured for decompressing compressed sector data as retrieved from the compressed computer memory in response to the sector request, and for providing the decompressed sector data to the selector unit and the sector merge unit;
wherein the selector unit is configured for obtaining data from the decompressed sector data using the address and size of said physical memory access request, and for returning the obtained data to the source of said physical memory access request in response to said read request;
wherein the sector merge unit is configured for obtaining data from the decompressed sector data using the address and size of said physical memory access request, for merging the obtained data with data in said physical memory access request into new uncompressed sector data, and for providing the new uncompressed sector data to the compressor; and
wherein the compressor is configured for compressing the new uncompressed sector data and storing it as said compressed sector data in the compressed computer memory in response to said write request.
