Abstract: This document describes apparatuses and techniques for termination of a pulse amplitude modulation signal of a memory circuit. In various aspects, a memory circuit is implemented with a termination circuit that includes a power rail, a resistor, and a switch to couple the resistor between the power rail and a signal line of a memory interconnect. The power rail may be configured to provide power at a termination voltage that is nominally half of a voltage of another power rail from which a corresponding transmission circuit operates. This may be effective to enable termination of pulse amplitude modulation signals to the termination voltage instead of a higher voltage that corresponds to the power rail of the transmission circuit or a ground-referenced node. By so doing, use of the termination circuit may reduce power consumption and/or improve signal integrity of the memory circuit.

Abstract: Methods, systems, and devices related to an improved driver for non-binary signaling are described. A driver for a signal line may include a set of drivers of a first type and a set of drivers of a second type. When the driver drives the signal line using multiple drivers of the first type, at least one additional driver of the first type may compensate for non-linearities associated with one or more other drivers of the first type, which may have been calibrated at other voltages. The at least one additional driver of the first type may be calibrated for use at a particular voltage, to compensate for non-linearities associated with the one or more other drivers of the first type as exhibited at that particular voltage.
