Abstract

A memory control system used for storage of data and a control method thereof are provided. The memory control system includes a memory unit including a plurality of memory cells storing data, a recording counter unit counting recording number for each memory cell of the memory unit, and a central processing unit (CPU). The CPU selects a first cell for the data recording operation when data recording operation is requested. The CPU determines whether a recording number of the selected first cell reaches a predetermined recordable threshold value. When the recording number of the selected first cell does not reach the recordable threshold value, the CPU performs the requested data recording operation to the selected first cell. When the recording number of the selected first cell reaches the recordable threshold value, the CPU selects a second cell different from the first cell and determining whether a recording number of the second cell reaches the recordable threshold value, and performs the requested data recording operation to the second cell when the recording number of the second cell does not reach the recordable threshold value.
