Abstract
A memory system is presented where sectors are normally stored in logically contiguous groups. As repeated writes of the same small sector group can causes a massive garbage collection (data relocation), the pattern of host access is monitored by checking the sectors' update history and control data structures' update history. When repeated access patterns are detected and then expected again, the “hot” segments are separated into specially handled, non-standard zone in the memory. The non-standard zone has a sector management that is different from the logical groups and optimized for the repeated host accesses in order to reduce the frequency and amount of garbage collection operations.
