Abstract
An apparatus may include a controller configured to communicate with a plurality of dies via a signal path. The controller may notify the dies of its desire to communicate with a target die. In response, the dies may set on-die termination resistances of two or more of the dies to a low resistance value, which in turn may set an overall termination resistance of the memory dies to be lower than the low resistance value. The lower overall termination resistance may be closer to a characteristic impedance of a portion of the signal path comprising packaging components of a packaging of the dies compared to the low resistance value, thereby reducing impedance mismatch between the characteristic impedance of the packaging components and the termination resistance.
