Working Principles

The JS28F256M29EWLD utilizes a floating gate transistor technology to store data. It uses a combination of electrical charges to represent binary information. When data is written, electrons are trapped in the floating gate, altering the transistor's behavior. This alteration allows the stored data to be retained even when power is removed. During read operations, the transistor's behavior is analyzed to retrieve the stored data.

Detailed Application Field Plans

The JS28F256M29EWLD is commonly used in various electronic devices that require non-volatile storage, such as:

1. Smartphones and tablets
2. Digital cameras
3. Solid-state drives (SSDs)
4. Automotive electronics
5. Industrial control systems

Its high capacity and fast read/write speeds make it suitable for applications that demand large amounts of data storage and quick access.

Alternative Models

1. JS28F512M29EWLD - 512 megabit (64 megabyte) capacity
