All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Research on charge trapping memory’s over erase

Acta Physica Sinica, 2014
In this paper, charge trapping memory (CTM) is studied for analyzing the over-erase phenomenon, based on the first principles and VASP package. The nitrogen vacancy (VN) in Si3N4 and the interstitial oxygen (IO) in HfO2 are selected as model, because of the formation energy.

ZnO based charge trapping memory with embedded nanoparticles [PDF]

2012 12th IEEE International Conference on Nanotechnology (IEEE-NANO), 2012
A thin film ZnO charge trapping memory cell with embedded nanoparticles is demonstrated by Physics Based TCAD simulation. The results show 3V increase in the V t shift due to the nanoparticles for the same operating voltage. In addition a ∼6V reduction in the programming voltage is obtained due the nanoparticles.

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

Advanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of
