A non-volatile semiconductor memory IC has both a flash memory and a CPU mounted thereon. The CPU is provided with a ROM which stores a program code and a memory device such as a SRAM. The CPU functions by the stored program code to perform various functions such as accessing the flash memory to thereby carry out a test to determine a good/bad condition of the flash memory, temporarily storing results of the test in the memory device, and copying the test results from the memory device into the flash memory.
