Abstract

Various implementations described herein are related to a device having wordline drivers coupled to a core array. The device may have backside power network with buried power rails. The device may have header logic coupled to power supply connections of the wordline drivers by way of the buried power rails, and the header logic may be used to power-gate the wordline drivers.
