Working Principle of W25Q256FVCIG TR

The W25Q256FVCIG TR flash memory is composed of two main parts, the memory cell array and the control circuit, as well as the input-output interface. The control circuit is mainly responsible for interfacing between the host and the flash memory, and for controlling/monitoring all the operations of the memory array. The memory cell array is composed of the cells for storing the information. Each cell consists of a floating gate MOSFET transistor that is used to store one bit of data.

The control circuit constantly monitors the state of the memory array, and when it gets an instruction from the host, it sends appropriate signals to the memory array to start the process. All read and write operations mediated by the control circuit are essentially operations of charging/discharging of the MOSFET transistors in the memory array. Then the specific operation is determined by the input/output voltage of the cell, whether it is a read operation or a write operation.

In the read operation, the control circuit will apply a specific impedance to the boundary of the cell, and then observe the current density to determine whether its state is 1 or 0. In the write operation, If a lower voltage is applied to the cell, the MOSFET transistor will enter a non-conductive state and the cell will store a logic 0; if a higher voltage is applied, the transistor will enter a conductive state and store a logic 1.

Conclusion

In conclusion, W25Q256FVCIG TR is a high performance and low power flash memory that is suitable for a variety of embedded system applications. Its integrated 8-bit parallel input/output interface allows for easy bus integration, and its read and write operations are based on the charging/discharging of the MOSFET transistors in the memory array. This makes it ideal for data storage in automotive, communication, industrial, and other applications.
