Abstract: Methods, systems, and devices that support variable modulation schemes for memory are described. A device may switch between different modulation schemes for communication based on one or more operating parameters associated with the device or a component of the device. The modulation schemes may involve amplitude modulation in which different levels of a signal represent different data values.

In one example, the device may switch from the first modulation scheme to the second modulation scheme when bandwidth demand is high, and the device may switch from the second modulation scheme to the first modulation scheme when power conservation is in demand. The device may also, based on the operating parameter, change the frequency of the signal pulses communicated using the modulation schemes.
