Working Principles

The AT28LV010-20JU chip utilizes a technology called electrically erasable programmable read-only memory (EEPROM). It stores data using floating-gate transistors that can be electrically programmed and erased. The stored data is retained even when power is removed, making it non-volatile.

To write data into the memory, a specific programming voltage is applied to the chip's pins. This causes the floating-gate transistors to trap charges, representing the desired data. Once programmed, the data can only be read and cannot be modified or erased.

During operation, the chip receives commands through its control pins (/CE, /OE, /WE) to enable reading or writing operations. The data stored in the memory can be accessed by providing the appropriate address inputs (A0-A16) and retrieving the corresponding data outputs (DQ0-DQ7).
