PROBLEM TO BE SOLVED: To execute a memory check with a small load on an embedded CPU.SOLUTION: A memory controller 6 is connected to a memory 8, and does not have an ECC (Error Check and Correct) function. An embedded CPU 4 is accessibly connected to the memory via the memory controller 6. A memory check circuit 10 is accessibly connected to the memory via the memory controller 6, and accesses the memory 8 in a non-operation period of the embedded CPU 4 to check data stored in the memory 8. |
