As for the working principle of JS28F640P33B85A non-volatile memory chip, it uses a charge-pump circuit to generate a voltage of 10V during programming. A stable voltage of 10V is applied to the control gates of the floating gates, thus supplying electrons to the floating gates to store data. During the reading mode, the control gates turn off and the electrons go back to the floating gates. The electrons flowing back to the floating gates cause the transistor to enter a non-magnetic state, resulting in a higher drain current, enabling the chip to read data.

In conclusion, JS28F640P33B85A is a high-performance non-volatile memory chip from STMicroelectronics with a wide range of application fields. It is mainly used in automotive electronics, digital consumer goods, medical electronics and smart card. Its working principle is based on the charge-pump circuit which is used to apply voltage to the control gates and the floating gates of the chip for the purpose of data stored. As the chip is one-time programmable, it can provide better security and accuracy for data storage.
