Abstract
The present invention discloses a compact three-dimensional memory (3D-M). By forming simple switching devices (e.g., pass transistors) on the address-select lines, contact vias can be shared by the address-select lines in the same memory level, or from different memory levels. This leads to sparser and fewer contact vias.
