Hardware‐Based On‐Chip Learning Using a Ferroelectric AND‐Type Array With Random Synaptic Weights
Advanced Intelligent Systems, EarlyView.This work demonstrates an energy‐efficient on‐chip learning system using an Metal‐Ferroelectric‐Insulator‐Semiconductor FeAND synaptic array. By employing a feedback alignment scheme with a separate backward array using fixed random weights, the system overcomes directional limitations of AND‐type arrays and achieves robust, low‐power learning suitable

A log-periodic fit for the flash crash of May 6, 2010 [PDF]
We show that a two-harmonic log-periodic formula fits the high-frequency data from the Dow Jones Industrial Average index, which encompass the recent episode known as the “flash crash†of May 6, 2010.flash crash, crashes, log ...

Advanced Intelligent Systems, EarlyView.This article introduces an input sparsity‐aware computing‐in‐memory macro featuring novel bidirectional conversion‐skippable analog‐to‐digital converters. By dynamically adjusting resolution based on element‐level sparsity, the architecture skips redundant most significant bit and least significant bit conversions.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation
Advanced Intelligent Systems, EarlyView.Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

A NOR Emulation Strategy over NAND Flash Memory
, 2007 快閃記憶體大致可分為兩類：NOR型快閃記憶體及NAND型快閃記憶體。一般而言，因為有就地執行（eXecute-In-Place，XIP）和快速讀取等特性，NOR型快閃記憶體應用上適用於儲存程式的可執行檔。而擁有較大容量與較快寫入速度的NAND型快閃記憶體則適用於資料儲存。此外，兩者在成本上有很大的差距，NOR型快閃記憶體相對於NAND型快閃記憶體高出許多。基於市場的趨勢，若能以較具經濟效益的NAND型快閃記憶體取代NOR型快閃，將可大幅地降低成本、提升毛利。在這篇論文中 ...

Ising Solver Using Vertical NAND Flash Memory
Advanced Intelligent Systems, EarlyView.Commercial V‐NAND flash memory is repurposed as a discrete‐time Ising solver by exploiting in‐memory current summation and read‐voltage‐controlled intrinsic noise. The system implements Hopfield neural‐network updates with simulated‐annealing‐like behavior, solving max‐cut problems with high accuracy and energy efficiency while using mass‐produced ...
