Abstract:
A solid state drive (SSD) includes an SSD control module configured to determine frequencies corresponding to how often data stored in respective logical addresses associated with the SSD is updated and form groups of the logical addresses according to the frequencies, and a memory control module configured to rewrite the data to physical addresses in blocks of an SSD storage region based on the groups.
