Storage control apparatus, storage apparatus, information processing system and processing method therefor

摘要

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.

1. A storage control apparatus comprising:
a processor; and a memory, the memory storing program code executable by the processor to perform operations comprising:
determining whether or not either one of an erase operation and a program operation is to be executed as pre-processing;reading out pre-read data from data area included in a memory cell to serve as a write-operation object prior to a write operation if a result of the determination indicates that the pre-processing is to be executed; andcarrying out the pre-processing and one of the erase operation and the program operations other than the pre-processing as post-processing if a result of the determination indicates that the pre-processing is to be executed, and carrying out the post-processing without carrying out the pre-processing if a result of the determination indicates that the pre-processing is not to be executed.
