Working Principles

The AT29LV040A-15TU-T utilizes a floating gate transistor technology to store data. It consists of an array of memory cells, each capable of storing one bit of information. The data can be written or erased by applying specific voltage levels to the control pins.

During programming, a high voltage is applied to the Write Enable (WE#) pin, allowing the data to be stored in the memory cells. Erasing is achieved by applying a higher voltage to the Chip Enable (CE#) and Output Enable (OE#) pins, which clears the stored data.
