How the data is deleted in the eeprom?

Data in EEPROM (Electrically Erasable Programmable Read-Only Memory) is deleted by applying a higher voltage to the memory cells, which allows the trapped charge to be removed from the floating gate of the memory transistor. This process typically involves erasing entire blocks or sectors of memory rather than individual bytes. The deletion is accomplished using a specific command sequence that triggers the erasure process, making the previously stored data inaccessible. After erasure, the memory cells return to their default state, ready to be reprogrammed with new data.
