Abstract
A one-time memory control apparatus is obtained that prevents erroneous opening of a fuse from causing logic conversion and enhances the reliability. The one-time memory control apparatus includes an opening current creation fuse C opening switch and an opening current creation fuse D opening switch that each allow a fuse opening current from a fuse opening current creation circuit to flow in response to an opening enable signal, and a fuse opening permission signal creation circuit that receives respective logic signals corresponding to the states of fuse opening currents that flow through an opening current creation fuse C and an opening current creation fuse D, and that creates a fuse opening permission signal.
