Abstract

Circuits and methods that use third dimension memory as a different memory technology are described. The third dimension memory can be used for application specific data storage and/or to emulate conventional memory types such as DRAM, FLASH, SRAM, and ROM or new memory types as they become available. A processor-memory system implements a memory operable as different memory technologies. The processor-memory system includes a logic subsystem and a memory subsystem, which includes third dimension memory cells. The logic subsystem implements memory technology-specific signals to interact with the third dimension memory cells as memory cells of a different memory technology. As such, the memory subsystem can emulate different memory technologies. The logic subsystem can be fabricated FEOL on a substrate and the memory subsystem can be fabricated BEOL directly on top of the substrate. An interlayer interconnect structure can electrically couple the logic subsystem with the memory subsystem.
