Abstract
A semiconductor storage system includes a memory controller that classifies a memory block of a memory area into a data block and a buffer block. The buffer block corresponds to the data block. The memory controller compares the number of free pages of both the data block and the buffer block with the number of valid pages of the data block and the buffer block during mergence in order to select the merged target block. Depending on the result of the comparison, either the data block or the buffer block is selected as the merged target block.
