摘要：
A memory control circuit according to an embodiment of the present invention includes: a writable/readable memory; a comparison unit comparing write data to write in the memory with read data that is read from a memory address where the write data is written; a comparison result storage unit storing a comparison result compared by the comparison unit in association with the memory address; and a control unit controlling retry processing of rewriting the write data to the memory address determined to be unverified based on the stored comparison result.
