Various implementations described herein are related to a device having memory circuitry with a bitcell array. The device may include a frontside power network that is coupled to the bitcell array, and the device may include a backside power network that provides power to the bitcell array. The device may include transition vias that couple the backside power network to the frontside power network, and the backside power network may provide power to the bitcell array by way of the transition vias being coupled to the frontside power network.
