Abstract
A method of managing a non-volatile memory device, the method comprising receiving data sectors; wherein each data sector belongs to a memory space subset out of multiple memory space subsets; wherein the multiple memory space subsets comprise a plurality of logical memory blocks; wherein the memory space is partitioned to the multiple memory space subsets based upon expected or monitored memory access patterns; writing each data sector into a data block that is allocated to a memory space subset that is associated with the data sector; wherein the data block belongs to a buffer of the non-volatile memory device; maintaining a management data structure that comprises location metadata about a location of each data sector in the buffer; and merging, if a criterion is fulfilled and before the buffer becomes full, data sectors stored at different data blocks and belong to a same set of logical memory blocks into a sequential portion of the non-volatile memory device, wherein the sequential portion differs from the buffer.
