Abstract
The present disclosure generally relates to apparatuses and methods for transmission line termination. In one embodiment an apparatus includes a stack of uniform memory dies and a storage controller. Each uniform memory die in the stack of uniform memory dies couples to a transmission line in series through wire bonds to form a transmission path. Each memory die includes an on-die termination resistance circuit connected to the transmission line. The on-die termination resistance circuit provides a minimum termination resistance. The storage controller addresses a target uniform memory die of the stack of uniform memory dies for an operation. The storage controller enables the on-die termination resistance circuits of a plurality of uniform memory dies along the transmission path. The storage controller transmits a data signal for the operation to the target uniform memory die with the on-die termination resistance circuit enabled for the plurality of uniform memory dies.
