A memory controller is connected to memory, and has no ECC (Error Check and Correct) function. An embedded CPU is connected to the memory via the memory controller such that it can access the memory. A memory check circuit is connected to the memory via the memory controller such that it can access the memory, and configured to access the memory in the non-operating period of the embedded CPU, so as to check the data stored in the memory.
