Abstract:
1. An error detection and correction apparatus, comprising: a code word read-out unit to execute read processing to read out a code word including a plurality of code elements that improve error correction capability by detection of an erasure position as read data from a memory address and to execute re-read processing to read out the code word as re-read data from the memory address after a predetermined time is elapsed from the time to read out the read data; a timing control erasure position detection unit to detect a position of the code element having a value not matched as the erasure position in the code word by determining whether or not the value is matched per the code word in the read data and the re-read data; and an error correction unit to correct an error based on the erasure position in the code word where the erasure position is detected.
