PROBLEM TO BE SOLVED: To provide a control circuit and a control method which protect a memory element having been mounted on a substrate and reset the protection. SOLUTION: This control circuit 1 is inserted into a signal line 7C1 of the memory element 7 having been mounted on the substrate and has an input part for signals 5a (RD, RST) transmitted by the signal line 7C1, a high-voltage input part 1b, an input part 1c for control signals 5b (OVP, RVP) for applying a high voltage V12, switch parts 1e and if which select the high voltage V12 as the high-voltage signals OVP and RVP when the control signals 5b are active and signals transmitted by the signal line when inactive, and an output part 1d which outputs the signals selected by the switch parts 1e and if.
