Working Principles

The JS28F064M29EWBA flash memory utilizes a floating gate transistor structure to store data. When programming, an electrical charge is applied to the floating gate, trapping electrons and altering the transistor's threshold voltage. This change in threshold voltage determines whether the cell represents a "0" or "1" bit. During read operations, the stored charge is measured to determine the stored data.

The JS28F064M29EWBA flash memory is commonly used in various electronic devices, including:

1. Solid-state drives (SSDs)
2. Digital cameras
3. Mobile phones
4. Tablets
5. Automotive electronics
6. Industrial control systems
