Abstract
Semiconductor devices are provided. The semiconductor device may include a current generation circuit and an internal circuit. The current generation circuit may include a first drive element and a second drive element which are connected in series. The current generation circuit may generate a reference voltage signal whose voltage level is set by a reference current which is identical or substantially identical to a current flowing through the first and second drive elements. The internal circuit may utilize an output current controlled according to the reference current as an operation current thereof.
