Abstract:
A solid state storage system includes a flash memory area and a memory controller. The flash memory area includes memory blocks and replacement blocks configured to replace bad blocks occurring within the memory blocks. The memory controller is configured to perform a logical-to-physical address mapping on logical blocks including the replacement blocks, and select the replacement blocks using logical addresses of the logical blocks corresponding to the bad blocks.
