  • A SUPER tutorial! If I had the chance to buy you that beer, jus, coke, or whatever beverage you prefer, I would!

  • Great write up! I am running into a problem however, when I try to read from the chip the log file is just "ÿ" repeated over and over again. Does this indicate any specific mistake on my part? I am going to try again with some different chips.

  • Hi there! Just wanted to say thank you so much for taking the time to explain this topic in such understandable and detailed way!!! I was studying on the 24lc256 eeprom and you clearify many questions I had.

      What a nice comment! You made our day. Thank you! Glad you got some good info from it.

  • Sadly, you can still "erase" most EEPROMs with radiation. But it takes higher energy radiation than the UV lamps for the EPROMS. MeV radiation will certainly destroy the storage mechanism. In EPROMs, the device can still be used, but requires reprogramming.
