Integrated circuit for storing information

摘要

An integrated circuit includes a variable resistance unit including at least one transistor that receives a control signal and changes a resistance through the transistor in response to the control signal in a programming operation mode and an information detection unit configured to detect programming information in response to an output voltage of the variable resistance unit in a normal operation mode.

1. An integrated circuit comprising:
a first variable resistance unit including first and second transistors configured to change resistances through the first and second transistors in response to first and second control signals in a programming operation mode, wherein the first and second transistors are commonly coupled to a first output terminal; a second variable resistance unit including third and fourth transistors configured to change resistances through the third and fourth transistors values in response to third and fourth control signals in the programming operation mode, wherein the third and fourth transistors are commonly coupled to a second output terminal; and an information detection unit configured to compare voltages of the first and second output terminals and detect programming information in a normal operation mode.
