Working Principle of W25Q64FVSF00

W25Q64FVSF00 NOR Flash Memory is designed to “read” digital data stored in its cells. Each cell stores a single bit of data. Each cell has two possible charge states, and the two states respectively represent digital 1 and 0. The read operation begins when the content of a row of cells is transferred into a shift register. If the Register address is specified, the desired cell output line can be selected by sending the cell address to the column gates. Once addressed, the charge on the floating gate of the cell being read is transferred to the First Output Transistor (Q1). The output voltage of Q1 is then buffered and sent to the output pad. After the cell contents are buffered, the output data is stable, and the cell reading operation is finished.

Data can be written to each cell with the write operation. During write, the selected cell float gate is charged until its threshold voltage is reached. When the cell’s threshold voltage is reached, the resistance of the transistor changes, allowing the write operation to complete.

W25Q64FVSF00 also provides erase operation. Full-Chips, Multi-Sector and Individual Sector Erase operations allow users to erase group or single bytes. After being erase, all the cells’ threshold voltage will restore to the original state.

Conclusion

W25Q64FVSF00 is a powerful and cost-effective Serial Flash memory device, providing an ideal non-volatile data storage solution for a wide range of product applications. The device can be used for read, write and erase operations, with good performance and low power consumption. W25Q64FVSF00 NOR Flash Memory is an ideal choice for size- and cost-constrained embedded applications.
