Liquid Silicon Silicon

Liquid Silicon is a computing paradigm enabled by monolithic 3D integration of 3D cross-point memory on silicon CMOS processors. It is in development at the University of Wisconsin-Madison[1] under a DARPA program.


The name “Liquid Silicon” was coined by Jing (Jane) Li[2], an assistant professor of electrical and computer engineering at UW-Madison. “Liquid means software and silicon means hardware. It is a collaborative software/hardware technique.”[1] It is developed to bridge the gap between computation and storage.

The Liquid Silicon chips incorporate memory, computation and communication into the same device using monolithic 3D integration: silicon CMOS circuitry on the bottom connected with solid-state memory arrays on the top using dense metal-to-metal links.
