Investigation of Re-Program Scheme in Charge Trap-Based 3D NAND Flash Memory

open access: yesIEEE Journal of the Electron Devices Society, 2021
Early retention or initial threshold voltage shift (IVS) is one of the key reliability challenges in charge trapping memory (CTM) based 3D NAND flash. Re-program scheme was introduced in quad-level-cell (QLC) NAND (Shibata et al., 2007, Lee et al., 2018,

Charge Loss Induced by Defects of Transition Layer in Charge-Trap 3D NAND Flash Memory

open access: yesIEEE Access, 2021
In charge-trap (CT) three-dimensional (3D) NAND flash memory, the transition layer between Si3N4 CT layer and SiO2 tunneling layer is inevitable, and the defects in the transition layer are expected to cause both lateral and vertical charge loss.

A Behavioral Compact Model of 3D NAND Flash Memory

open access: yesCoRR, 2018
We present a behavioral compact model of 3D NAND flash memory for integrated circuits and system-level applications. This model is easy to implement, computationally efficient, fast, accurate and effectively accounts for the different parasitic capacitance coupling effects applicable to the 3D geometry of the vertical channel Macaroni body charge-trap ...

A Unified Flash Memory Platform for Mode‐Adaptive and Robust AI Computation

open access: yesAdvanced Science, EarlyView.
A unified AND‐type flash memory platform enables both transistor‐mode and capacitor‐mode computing‐in‐memory operations within the same device structure. By selectively switching the sensing mode through peripheral reconfiguration, the platform provides adaptable trade‐offs between computational accuracy, robustness, and energy efficiency for AI ...
