3D semiconductor memory device and structure

Abstract

A 3D semiconductor device, the device including: a first level including first single crystal transistors; a second level including second transistors; memory periphery circuits; and memory cells, where the first level is overlaid by the second level, where the first level includes a transferred layer and a bonded layer, where the second level is bonded to the first level, where the bonded second level includes oxide to oxide bonds, where the bonded second level includes metal to metal bonds, where the first level includes a preponderance of the memory periphery circuits, where the second level includes a preponderance of the memory cells, where the preponderance of the memory periphery circuits are connected to the preponderance of the memory cells using a portion of the metal to metal bonds, and where the memory periphery circuits include at least one Look up Table (“LUT”) circuit.
