Abstract

An apparatus and method providing independent control of on-die termination (ODT) of output buffers. The ODTs for the buffer circuits of an input/output (I/O) buffer can be enabled and disabled in response to an ODT control signal. Additionally, the ODTs for a first set of the buffer circuits can be enabled and disabled responsive to the ODT control signal and the ODT for at least one of a second set of the buffer circuits is disabled.
