Abstract
A memory controller and methods for managing efficient writing to a flash memory are presented. Fresh data is written to at least one block of the flash memory. During a space reclamation process, other data, previously written to the flash memory, is relocated to at least one other block of the flash memory, such that the fresh data and the relocated data always are maintained in separate blocks of the flash memory. During writing, an update frequency level is selected for the fresh data from among multiple update frequency levels and the fresh data is written to a block that is associated with the selected update frequency level. During space reclamation, a plurality of blocks, space of which is to be reclaimed, is selected and the valid pages thereof are copied to at least one destination block.
