Assignee: SUNRISE MEMORY CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A memory device, comprising:
a memory circuit formed on a planar surface of a semiconductor substrate, the memory circuit comprising a plurality of modular memory units, each modular memory unit comprising a three-dimensional array of storage transistors, each storage transistor being accessed by a word line and a bit line; and
support circuitry for the memory circuit formed in the semiconductor substrate under the memory circuit, the support circuitry comprising a plurality of modular circuit units, each modular circuit unit being formed underneath an associated one of the modular memory units to support memory operations of that modular memory unit,
wherein each modular memory unit is configurable to be operated independently by the associated modular circuit unit to perform memory operations and two or more modular memory units are configurable to be operated in parallel by their respective associated modular circuit units to perform memory operations.
