Abstract

Various implementations described herein are related to a device with a frontside power network and a backside power network. The frontside power network may include frontside supply rails coupled to logic circuitry, and also, the backside power network may include buried supply rails. Also, at least one buried supply rail of the buried supply rails may be used as a backside signal path for providing at least one critical signal net to the logic circuitry.
