Working Principles

The 25LC080A-I/MS utilizes an electrically erasable floating gate technology to store data. When a byte of data needs to be written, an electrical charge is applied to the floating gate, altering its threshold voltage. This change in threshold voltage represents the stored data bit. During read operations, the threshold voltage is measured to determine the stored data.
