Abstract
Techniques are presented to allow non-volatile memory system to operate by determining ranges of logical addresses that a host typically accesses as together. For example, the system's controller can determine that the host always, or most always, writes or reads a contiguous set of logical addresses as a single unit. The controller can exploit this information by operating on these ranges as single a unit for data operations it performs. To take one example, the memory system can treat such ranges as single units for on-system data compression prior to writing the data to non-volatile memory.
