Analysis and Modeling of Internal State Variables for Dynamic Effects of Nonvolatile Memory Devices

open access: yesIEEE Transactions on Circuits and Systems I: Regular Papers, 2012
Hybrid integration of CMOS and nonvolatile memory (NVM) devices has become the foundation for emerging nonvolatile memory-based computing. The primary challenge to validate hybrid memory system with both CMOS and NVM devices is to develop a SPICE-like ...

Endurance-Aware Allocation of Data Variables on NVM-Based Scratchpad Memory in Real-Time Embedded Systems

open access: yesIEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2015
Nonvolatile memory (NVM) has many benefits compared to the traditional static RAM, such as improved reliability and reduced power consumption, but it has long write latency and limited write endurance. Scratchpad memory (SPM) is software-managed small on-

Quantum Dot Channel (QDC) Field Effect Transistors (FETs) Configured as Floating Gate Nonvolatile Memories (NVMs)

Microelectronics and Optoelectronics, 2017
This paper presents quantum dot channel (QDC) Field Effect Transistors (FETs) which are configured as nonvolatile memories (NVMs) by incorporating cladded GeOx-Ge quantum dots in the floating gates as well as the transport channels. The current flow and the threshold characteristics were significantly improved when the gate dielectric was changed from

Fabrication and Operation Methods of a One-time Programmable (OTP) Nonvolatile Memory (NVM) Based on a Metal-oxide-semiconductor Structure

Journal of the Korean Physical Society, 2011
In this paper, a novel one-time programmable (OTP) nonvolatile memory (NVM) device and its array based on a metal-insulator-semiconductor (MIS) structure is proposed. The Iindividual memory device has a vertical channel of a silicon diode. Historically, OTP memories were widely used for read-only-memories (ROMs), in which the most basic system ...

Characterization of moving bits (MBs) and QBD in wet/dry tunnel oxides for floating gate type nonvolatile memory (FG-NVM) applications

Solid-State Electronics, 2004
Abstract A critical problem of floating gate type nonvolatile memories (FG-NVMs) used in flash memories or EEPROMs is anomalous charge loss which leads to threshold voltage (Vt) shifts on a time scale of months or years at room temperature. The number of these moving bits (MB's) is greatly affected by the nature and properties of the tunnel oxide ...

Nonvolatile Memory (NVM) Operation of Tunnel Field-Effect Transistor (TFET) Using Ferroelectric HfO₂ Sidewall.

Journal of nanoscience and nanotechnology
In this paper, we propose a new type of nonvolatile memory (NVM) device based on a tunnel field-effect transistor (TFETs) with Ferroelectric HfO₂ sidewall. By simply utilizing the ferroelectricity of orthorhombic HfO₂ and conventional sidewall spacer technique, TFET can operate as a NVM device.
