Working Principles

AT28C010E-20PI operates based on the principle of electrically erasable programmable read-only memory (EEPROM). It uses a combination of transistors and floating gate technology to store and retrieve data.

When programming, a high voltage is applied to the control gates, allowing electrons to tunnel through the insulating layer onto the floating gate. This process traps the charge, representing a logical "1" in the memory cell. Erasing the memory involves removing the trapped charge from the floating gate.

During normal operation, the chip enables the reading of data by applying appropriate voltage levels to the control gates and accessing the stored information.
