Abstract
Various implementations described herein are related to a device having bitline drivers coupled to passgates of bitcells via bitlines and buried metal lines formed within a substrate including a buried enable signal line and a buried ground line coupled to ground connections of the bitline drivers. The buried enable signal line transfers a negative bias to a selected bitline of the bitlines via the buried ground line that is coupled to the ground connections of the bitline drivers so as to increase gate-source bias of the passgates of the selected bitcell to thereby enhance write capability of the selected bitcell.
