<p>In a microcomputer, a programmable memory (10) such as a flash EEPROM has a first memory region (block 1 to block 3) and a second memory region (block 0). In this case, the first memory region stores an application program, while the second memory region stores a boot program for rewriting the application program. Under this condition, a selecting circuit (17) selects only the first memory region for erasure.</p> |
