Claim 5:
6. The device for accessing compressed computer memory as defined in claim 5, wherein the selector unit comprises a decision function configured for making a decision for causing the compressed address calculator unit and the sector request unit to selectively make a sector-based read request, a sub-sector-based read request or a block-based read request to the compressed computer memory, the decision function being operative to make said decision based on any of the following:
monitored compressibility of the compressor,
monitored memory access pattern,
utilization of a prefetch buffer configured for buffering all or some of the decompressed sector data resulting from a physical memory access request,
an evaluation of compression ratio of the requested sector in relation to its uncompressed physical size, and
an evaluation of compression ratio of the requested sector in relation to its uncompressed physical size and average metadata per request.
