In the ever-evolving world of electronics, data storage plays a crucial role. Non-volatile memories (NVMs) have emerged as indispensable components for storing information that persists even when power is removed. Among the various NVM technologies, charge trapping non-volatile memories (CTNVMs) stand out for their unique operating principles, high performance, and wide-ranging applications.

This comprehensive guide delves into the fascinating world of CTNVMs, exploring their fundamental concepts, operating mechanisms, advantages, limitations, and diverse applications. By shedding light on the intricacies of this technology, we aim to empower readers with a thorough understanding of CTNVMs, enabling them to leverage its capabilities effectively in their research and development endeavors.

Fundamentals of Charge Trapping Non Volatile Memories

Basic Principles

CTNVMs utilize the principle of charge trapping to store information. They consist of a floating gate (FG) sandwiched between two dielectric layers: a control oxide (COX) and a tunnel oxide (TOX). When a positive voltage is applied to the control gate (CG),electrons from the source are injected through the TOX into the FG, creating a negative charge. Conversely, when a negative voltage is applied to the CG, electrons are repelled from the FG, resulting in a positive charge.

Operating Mechanisms

CTNVMs operate through two primary mechanisms:

Program: Positive voltage on the CG injects electrons into the FG, creating a negative charge.
Erase: Negative voltage on the CG repels electrons from the FG, creating a positive charge.

The amount of charge trapped in the FG determines the memory state. By reading the voltage on the FG, the stored information can be retrieved.

Advantages of Charge Trapping Non Volatile Memories

CTNVMs offer several compelling advantages:

High Speed and Low Power Consumption: They enable fast programming and erasing operations, consuming minimal power.
