Abstract
An internal voltage detection circuit and an internal voltage generation device using the same are disclosed. The internal voltage detection circuit includes a first detect signal generator for generating a first detect signal to detect a level of an internal voltage corresponding to an operating temperature of a memory cell, a second detect signal generator for generating a second detect signal to detect a specific level of the internal voltage corresponding to a preset temperature, and a detect signal clamp unit for comparing a level of the first detect signal and a level of the second detect signal with each other and clamping the first detect signal according to a result of the comparison.
