Abstract
Provided are an on-chip termination apparatus in a semiconductor integrated circuit, and a method for controlling the same. The on-chip termination apparatus is installed in a semiconductor integrated circuit that has an output driver for outputting data to the outside via a pad and a data input circuit for receiving data from the outside via the pad. The on-chip termination apparatus includes an on-chip terminator including at least one terminal resistor electrically connected to the pad; and a terminator control circuit for turning on or off the on-chip terminator in response to an output enable signal that enables or disables the data output circuit, wherein the terminator control circuit turns off the on-chip terminator in the event that the data output circuit is enabled. Therefore, the on-chip termination apparatus is controlled by an output enable signal, thereby reducing timing loss, thus enabling a system to operate at high speed.
