Abstract
An apparatus may include a controller die configured to communicate with a plurality of dies via a transmission line. The controller die may be configured to transmit a signal on the transmission line to a target die of the plurality of dies, or the target die may transmit a signal on the transmission line. The transmission may be dependent on an end die of the plurality of dies setting an end-die termination resistance to a low level. In situations where the target memory is receiving the signal, the target die may set target an on-die termination resistance to a high level. In situations where the target memory die is transmitting the signal, the target die may set an on-die termination resistance to a low level.
