IPC: G06F11/00
Filed: 1981-02-19
Abstract: PURPOSE:To surely perform prevention of mis-write at main power supply failure, by inhibiting a memory driving signal quickly when the main power supply  falls. CONSTITUTION:When a main power supply 8 falls and a main power supply voltage VCC is a preset value or less, a main power supply voltage failure detecting signal VDS is outputted from a main power supply voltage failure detecting circuit 1, a switch circuit 5 is opened and the power supply for the final stage gate 3 of a memory drive circuit 2 is interrupted. Thus, the gate 3 performs no function and the memory drive signal MCS is kept at high level and inhibited with pull-up of a battery voltage VBB. Thereafter, when the main power supply voltage lowers, even if a mis-output is outputted from the circuit 2, since the final stage gate does not perform the function, the effect is not given on a memory cell 4. Thus, mis-write to the memory can be prevented.
