Working Principles

The JS28F640J3D75A utilizes a floating gate transistor technology to store data. It employs a grid of transistors, where each transistor represents a memory cell. The presence or absence of an electrical charge on the floating gate determines the stored data value (0 or 1). The control gates and other circuitry allow for reading, writing, and erasing operations on the memory cells.

Application Field Plans

The JS28F640J3D75A is commonly used in various electronic devices that require non-volatile data storage, such as:

1. Embedded Systems
2. Consumer Electronics
3. Automotive Applications
4. Industrial Control Systems
5. Networking Equipment
