Abstract
There is provided a fuse module that holds trimming information for an internal oscillation circuit module. The fuse module includes information-writing fuse circuits to which trimming information is written depending on whether an information-writing fuse is blown; a reference fuse circuit for determining whether the information-writing fuse has been blown; and a current-to-voltage converter section. Since the reference fuse circuit and the current-to-voltage converter section are shared by the information-writing fuse circuits, the circuit area of the fuse module is greatly reduced.
