Dynamic voltage selection for memory systems

A memory system, comprising:

• a controller mounted to a substrate;
• one or more memory devices mounted to the substrate and coupled with the controller;
• a first interface of the substrate comprising a first power supply input, a second power supply input, and a third power supply input, wherein the first power supply input and the second power supply input are coupled with the one or more memory devices and provide power for one or more first components and one or more second components of the one or more memory devices at a first voltage level and a second voltage level, respectively, and wherein the third power supply input is coupled with the controller and provides power for one or more components of the controller at a third voltage level;
• and
• a second interface of the substrate comprising a plurality of pins configured to be coupled with a corresponding interface of a host system and the controller, the controller operable to monitor a plurality of operating parameters and to output a combination of signals in accordance with one or more operating parameters of the plurality of operating parameters, the combination of signals indicating a set of voltage levels of a plurality of sets of voltage levels, wherein each of the plurality of sets of voltage levels comprises settings for the first voltage level, the second voltage level, and the third voltage level.
