Abstract
A solid state storage system includes a flash memory region comprising a plurality of memory blocks and a plurality of replacement blocks corresponding to error-occurred blocks when errors occur in the memory blocks; and a memory controller configured to perform a control operation to replace the error-occurred blocks with the replacement blocks, wherein the error-occurred blocks comprise correctable blocks and uncorrectable blocks, and wherein the memory controller determines whether the error-occurred blocks are the correctable blocks or the uncorrectable blocks and controls zones of the replacement blocks, replaced in correspondence to the correctable blocks, to be allocated a plurality of times.
