ABSTRACT:
In a microcomputer, a programmable memory such as a flash EEPROM has a first memory region and a second memory region. In this case, the first memory region stores an application program, while the second memory region storing a boot program for rewriting the application program. Under this condition, a selecting circuit selects the first memory region except the second memory region. Further, only the selected first memory region is erased.
