IPC: H01L21/822
Filed: 1989-06-07
Abstract: PURPOSE:To enable a signal to be transferred to the other semiconductor circuit in normal logic level by a method wherein a means capable of changing a partial inner function when a resistor row having a specific polarity is impressed with an outer signal in inverse polarity is provided. CONSTITUTION:An input terminal 14 is impressed with an input I+ to connect the electrode of a switch S2 while a reference voltage V+ of another input terminal 13 is connected to the electrode of another switch S1. Furthermore, another input I0 is connected to the electrode of the other switch S4 i. e., an input terminal 16 while the other input terminal 15 is connected to the electrode of the other switch S3. At this time, the switches S1 and S3 as well as the switches S3 and S4 are in the same phase while the group of S1 and the group of S2 are in the inverse phase. When the signal to transfer the polarity of switches S1-4 is inputted in the transfer circuit, the former expression of I+= v+>I-=V- is changed into the other expression of 1+= I1<I-=Io to change the output in an IC thereby enabling the signal to be inputted in this IC. Through these procedures, a signal can be transferred to the other semiconductor circuit at a normal logic level.
