Title: Memory contents protecting circuit
Inventor: MARU TSUGIO
IPC: G06F21/62
Filed: 1988-01-11
Abstract: PURPOSE:To prevent the storing contents of a specified address from being destroyed by prohibiting a writing to the specified address of a memory when a prescribed signal is not generated at the time of the writing to a rewritable memory. CONSTITUTION:When data are written to an address A of a RAM11, an FF1 and a decoder 2 output '1' and the output of a NAND gate 43 goes to be '1'. Then, a NAND gate 4 outputs the condition of a terminal -WR of a CPU12 to the RAM11 as it is and the writing can be executed. Even when the CPU12 executes a runout, the address A is designated by the address data of a bus 15 and even if the condition of the terminal -WR of the CPU12 goes to be '0', in case that the output of a gate 3 is '0', a writing terminal signal is prohibited from being inputted to the RAM11. Accordingly, the RAM11 goes to be unwritable and the storing contents of the address A of the RAM11 are protected from the runout of the CPU12.
