Abstract
A storage control apparatus includes: a pre-processing-execution determining block for determining whether or not either one of an erase operation and a program operation is to be executed as pre-processing in a write operation to be carried out on a predetermined data area to serve as a write-operation object; and a pre-read processing block for reading out pre-read data from the data area prior to the write operation if a result of the determination indicates that the pre-processing is to be executed. The apparatus further includes a bit operating block for carrying out: the pre-processing and one of the erase and program operations which is not the pre-processing as post-processing if a result of the determination indicates that the pre-processing is to be executed; and the post-processing without carrying out the pre-processing if a determination result indicates that the pre-processing is not to be executed.
