Abstract
High-efficiency control technology for non-volatile memory is shown. A controller allocates spare blocks of a non-volatile memory to provide a first active block and writes data issued by a host to the first active block. When the number of spare blocks is less than a threshold number and valid data of a first source block is less than a critical data amount, the controller uses the first active block as a data transfer destination for the valid data from the first source block.
