Abstract
An apparatus includes a controller die and a group of dies that communicate with each other via a transmission line. Less than all of the dies of the group includes a respective on-die termination resistance circuit coupled to the transmission line. In some embodiments, one of the dies that includes an on-die termination resistance circuit is an end die of the group. In particular embodiments, the end die is the only die of the group that includes an on-die termination resistance circuit coupled to the transmission line. Transmission frequencies or data rates may be increased without degrading signal quality by removing capacitance associated with on-die termination resistance circuits from at least one of the dies of the group.
