Working Principles

The W25Q128JVBIQ operates based on the principles of Flash memory technology. It utilizes a floating-gate transistor structure to store digital information. The memory cells are organized into sectors, which can be individually erased or programmed. Data is written by applying voltage to the appropriate memory cells, and it can be read by detecting the electrical state of these cells.
