<p>PURPOSE:To clear the storage contents of a memory with a single program instruction and to decrease the program steps by increasing the address data which is used to give the access to the memory address for each access period of the memory. CONSTITUTION:A flag storage means 4 is provided together with an access control means 7, an address setting means 11, and a resetting means. When a clear command signal is outputted to clear the storage contents of a memory 2, the address data is successively increased for the access to the address of the memory 2 for each access period of the memory 2 set based on the control output of the means 7. Thus the storage contents of the memory 2 can be cleared just with a single program instruction.</p> |
