<p>PROBLEM TO BE SOLVED: To make comprehensiveness in memory error detection compatible with efficiency.SOLUTION: A memory access device 20 acquires data stored in a first address of a memory 14 on the basis of a request from a signal processing part 12 and determines normality of the data on the basis of redundant information corresponding to the data. When acquiring data stored in the first address, the memory access device 20 further acquires data stored in a second address that is independent of the first address and indicates a region in the memory 14 where normality should be confirmed. The memory access device 20 further determines normality of data stored in the second address on the basis of redundant information corresponding to the data.</p> |
