Abstract:
1. A resistor circuit comprising: first to Mth (M is an integer equal to or larger than two) resistor circuit units that are provided in series between a first node and an (M+1)th node, a (2j−1)th (1≦2i−1<M) resistor circuit unit among the first to Mth resistor circuit units including: a (2j−1)th first fuse element and a (2j−1)th resistor that are provided in series between a (2j−1)th node and a 2jth node; and a (2j−1)th second fuse element that is provided in parallel with the (2j−1)th first fuse element and the (2j−1)th resistor between the (2j−1)th node and the 2jth node; a 2jth resistor circuit unit among the first to Mth resistor circuit units including: a 2jth first fuse element and a 2jth resistor that are provided in series between the 2jth node and a (2j+1)th node; and a 2jth second fuse element that is provided in parallel with the 2jth first fuse element and the 2jth resistor between the 2jth node and the (2j+1)th node; the (2j−1)th first fuse element, the (2j−1)th second fuse element, the 2jth first fuse element, and the 2jth second fuse element being disposed in a fuse region; the (2j−1)th resistor being disposed in a first resistor region that is formed in a first direction with respect to the fuse region; and the 2jth resistor being disposed in a second resistor region that is formed in a third direction with respect to the fuse region, the third direction being a direction opposite to the first direction.
