Fuse element reading circuit |
摘要 |
A fuse element reading circuit including a first fuse element having a resistance which differs in accordance with whether the first fuse element is in a blown state or an unblown state, a reference voltage output circuit unit that outputs a reference voltage that differs in accordance with a normal mode or a test mode, and a voltage comparison circuit unit that compares a read voltage corresponding to the resistance of the first fuse element with the reference voltage output from the reference voltage output circuit unit. |
