THE ADDRESS TRANSITION DETECTION CIRCUIT

摘要

Transistor circuit for a semiconductor device with hysteresis operation comprises: a detector for generating an output signal in response to an input signal between two threshold levels, and a selector for selecting one of the threshold levels in accordance with the output signal and applying it to the detector. Device is made by a process in which no shallow implantation in the NMOS transistor fabrication step of a CMOS process is applied to a transistor having a low threshold voltage.
