Working Principles

The PC28F00AP33BFA flash memory operates based on the principles of floating-gate transistors. It utilizes a grid of memory cells, each consisting of a floating gate and a control gate. The presence or absence of an electric charge on the floating gate determines the stored data.

During programming, a high voltage is applied to the control gate, allowing electrons to tunnel through the insulating layer onto the floating gate. This process traps the charge, representing a binary value (0 or 1). Erasing the memory involves removing the trapped charge from the floating gate.

Data retrieval is achieved by applying appropriate voltages to the control gate and reading the resulting current flow. The stored charge alters the conductivity of the transistor, enabling the detection of the programmed data.
