Working Principles

The M27C4002-10C1 utilizes a technology called floating-gate MOSFET to store data. It consists of an array of memory cells, each capable of storing a single bit of information. 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 either a "0" or a "1". During read operations, the stored charge is sensed, and the corresponding data is retrieved.
