Working Principles

The W25Q257FVFIG TR operates based on the principles of flash memory technology. It utilizes floating-gate transistors to store digital information. When data is written, charges are trapped in the floating gate, altering the transistor's conductive properties. This change in conductivity allows the device to retain the written data even when power is removed. During read operations, the stored charges are detected, enabling the retrieval of the stored information.
