Working Principles

The AT93C46EN-SH-T utilizes an electrically erasable technology that allows individual bits of data to be erased and reprogrammed. It uses a combination of transistors and capacitors to store binary information. When a write operation is initiated, the chip applies a high voltage to the selected memory cell, altering its charge state and storing the desired data. During read operations, the chip retrieves the stored data by sensing the charge level of each memory cell.
