Assignee: BESANG, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A 3D NVM module, comprising:
a logic layer formed on a substrate and comprising a memory control circuit;
blocks of conductive film disposed over said logic layer;
semiconductor pillars formed and arranged in an array on each of said blocks of conductive film, and forming bodies of vertical transistors;
a tunneling dielectric disposed on at least a portion of each of said semiconductor pillars;
a coupling dielectric disposed over said tunneling dielectric;
a control gate disposed on said coupling dielectric and surrounding a middle portion of each of said semiconductor pillars;
a first set of 3D vias formed on said logic layer outside or between said blocks of conductive film;
a first set of metal lines disposed over said semiconductor pillars and on said first set of 3D vias;
and wherein:
said array has a bit-line direction and a word-line direction, perpendicular to each other;
said first set of 3D vias are coupled to said memory control circuit;
said first set of metal lines stretch in said bit-line direction; and
each of said first set of metal lines couples said one or more of said first set of 3D vias to a respective group of said semiconductor pillars that are along a respective line stretching in said bit-line direction.
