Working Principles

The AT27C010-70JI operates based on the principle of electrical charge trapping. During programming, a high voltage is applied to the selected address pins, causing electrons to be trapped in the floating gate of the memory cell. These trapped charges represent the stored data. During read operations, the presence or absence of trapped charges is detected, allowing the retrieval of the programmed data.
