    Abstract: Apparatuses and methods for providing additional drive to multilevel signals representing data are described. An example apparatus includes a first driver section, a second driver section, and a third driver section. The first driver section is configured to drive an output terminal toward a first selected one of a first voltage and a second voltage. The second driver section configured to drive the output terminal toward a second selected one of the first voltage and the second voltage. The third driver section configured to drive the output terminal toward the first voltage when each of the first selected one and the second selected one is the first voltage. The third driver circuit is further configured to be in a high impedance state when the first selected one and the second selected one are different from each other.

    Abstract: Apparatuses and methods for a multi-level communication architectures are disclosed herein. An example apparatus may include an input/output (I/O) circuit comprising a driver circuit configured to convert a first bitstream directed to a first memory device and a second bitstream directed to a second memory device into a single multilevel signal. The driver circuit is further configured to drive the multilevel signal onto a signal line coupled to the first memory device and to the second memory device using a driver configured to drive more than two voltages.

    Abstract: Memory devices and methods of making and operating them are shown. Memory devices shown include stacked memory dies with one or more buffer dies included. In one such memory device, a command die communicates with one or more downstream memory dies through the one or more buffer dies. The one or more buffer dies function to repeat signals, and can potentially improve performance for higher numbers of memory dies in the stack.

    Abstract: Apparatus are disclosed, such as those involving a transmitter circuit that is configured to generate multi-level signals based on a plurality of data digits. One such transmitter circuit includes a signal output and an encoder configured to provide control signals based at least partially on the plurality of data digits. The transmitter circuit also includes a first set of switches configured to receive one or more of the control signals, and to selectively conduct a first or second voltage reference to the signal output. The transmitter circuit further includes first and second voltage drop circuits that provide third and fourth voltage references, respectively. The third and fourth voltage references have voltage levels between those of the first and second voltage references. The transmitter circuit also includes a second set of switches configured to receive one or more of the control signals, and selectively conduct the third or fourth voltage reference to the signal output.
