ABSTRACT:
A semiconductor integrated circuit has a flash interface for receiving command codes and controlling a flash memory to perform corresponding read, write, and erase operations. The flash interface generates a status signal indicating whether the flash memory is currently being controlled or not. The flash interface includes an address circuit for input and output of flash memory addresses, a status circuit that generates the status signal, and a resetting circuit that resets the status signal to the non-control state according to an address output from the address circuit. This hardware feature is used to halt write operations at the maximum address without the need for a halting command, and to prevent consecutive erasing of the same part of the flash memory.
