Diffusive Memristor as a Synapse

Neuromorphic computing, systems designed to mimic the biological nervous system, require far less power than current computer processors. The increased efficiency makes feasible artificial intelligence applications for smaller, hand-held devices (e.g. smartphones, tablets). To this end, UMass inventors have designed hardware components that mimic neuronal...

Memristor Random Number Generator

True random number generators (TRNGs) are used in cryptography and cyber security, and are increasingly important in an interconnected world at risk from cyber threats. Hardware random number generators use physical variables, such as thermal noise or the photoelectric effect, as sources of randomness in number generation. However, they suffer from...

Neuromorphic Computing Memristive Device

Resistance switching devices, also known as memristive devices, represent the next generation in computing. With a typical metal/insulator/metal structure, memristors change resistance based on past current flow and retain this new resistance even when turned off. This allows memristors to store data without needing constant power like in traditional...

Method OF Transfer Printing

2-dimensional (2D) materials are characterized as being one or two atoms thick. Graphene (image) is by far the best known 2D material. However, there are many other 2D materials with attractive properties (e.g. hexagonal boron nitrides (hBN), transition metal dichalcogenides, etc.). Due to their superior physical properties, graphene and related 2D...

Extremely Small and Fast Radio Frequency Switches

TECHNOLOGY DESCRIPTIONMemristive devices are characterized by their present resistance being dependent on the current that last passed through them. In this invention, a memristive RF switch is created by having two micro-electrodes with a small air gap, e.g., 50nm or less, between them. When in the “off” state, the air gap between the...

All Silicon Based Memristive Devices and Arrays

A new low power resistance random access memory (RRAM) device based on silicon materials has been invented. RRAM devices are non-volatile memory devices as well as promising candidates to replace FLASH memory and become the front runner among non-volatile memories. Instead of charge storage, RRAM uses high and low resistance as state variables. RRAM...

Method for Self-Repair of Defects in Nano-Structures

Researchers at Princeton University have developed a new method for repairing and thereby reducing defects in a patterned nanoscale device by liquifying the patterned device in the presence of appropriate guiding conditions for a period of time and then permitting the device to re-solidify. The performance of such nanoscale devices typically...
