ELECTRONIC DEVICES COMPRISING BLOCKING REGIONS, AND RELATED ELECTRONIC SYSTEMS AND METHODS

An electronic device comprising one or more blocking regions. The electronic device also comprises a source stack comprising one or more conductive materials, a source contact vertically adjacent to the source stack, and a doped semiconductive material vertically adjacent to the source contact. Tiers of alternating conductive materials and dielectric materials are vertically adjacent to the doped semiconductive material, and pillars extend through the tiers of alternating conductive materials and dielectric materials, the doped semiconductive material, and the source contact and into the source stack. The one or more blocking regions are laterally adjacent to the semiconductive material. Additional electronic devices, electronic systems, and methods are also disclosed.
