FLASH MEMORY AND MEMORY CONTROL METHOD

摘要

The state inside a flash memory is reported to outside and a garbage collection is supported. A state report information generation unit (12) references flag areas f1, f2, f3, ..., fn and generates state report information for reporting outside information according to the state of user areas u1, u2, u3,..., un. An output unit (13) outputs the state report information so as to report the state inside the flash memory (10) to outside.
