Working Principles

The JS28F256P33B95A is based on NAND flash memory technology. It stores digital information by trapping electrons in a floating gate, which can be electrically programmed and erased. When reading data, the stored charge is detected and converted into binary information. The device utilizes a parallel interface for communication with the host system.

Detailed Application Field Plans

The JS28F256P33B95A is widely used in various electronic devices that require non-volatile storage, such as:

1. Embedded systems
2. Consumer electronics (e.g., smartphones, tablets)
3. Automotive applications (e.g., infotainment systems, instrument clusters)
4. Industrial control systems
5. Medical devices
