Abstract
An error detection device includes a generation unit and a detection-correction unit. When writing data into a storage unit, the generation unit generates error detection information for each piece of division-data into which write-data are divided. The error detection information is information which is available in determining whether a bit error includes in the division-data, and by which a position where the bit error is caused can be detected based on plural pieces of the error detection information of the plural division-data composing the write-data. Using the error detection information, the detection-correction unit can determine whether the bit error is caused in the division-data. Using plural pieces of the error detection information of the data including the division-data in which it is detected that the bit error is caused, the detection-correction unit can detect the position where the error is caused, and can correct the bit error.
