To erase data from an EEPROM device, a negative pulse is applied, which causes the electrons to tunnel back out and return the floating gate to near its original state. With the COMSOL® software, you can simulate this program and erase process and calculate many different EEPROM device characteristics.

Which technique is used to erase the data in eeprom memory?

EEPROM also uses floating gate technology. Its dimensions are finer, so that it can exploit another means of charging its floating gate. This is known as Nordheim–Fowler tunnelling (NFT). With NFT, it is possible to electrically erase the memory cell as well as write to it.

How do I manually delete EEPROM?

EPROM typically is burned out-of-circuit in a programming fixture. When the time comes to erase the EPROM, just pop it under an ultraviolet (UV) bulb for 30 minutes, and you're ready to go again. The EPROM's quartz window allows UV light to strike the silicon die, erasing the memory.
