Working Principles

The PC28F00AP33TFA flash memory utilizes a floating-gate transistor structure to store and retrieve data. It employs a combination of electrical charges to represent binary information. During programming, electrons are trapped in the floating gate, altering the transistor's conductive properties. This change allows the memory cell to retain its state even when power is removed. Reading data involves applying appropriate voltages to the memory cells and sensing the resulting current flow.
