This is an experiment we made some months ago.<\/p>\n

It’s about a damaged EPROM. It was inserted backwise into his socket, so it was burned. We saw it and we had an idea… <\/p>\n

The EPROM was crack-opened by the owner. A microscope image show us that connections in +Vcc and Ground were interrupted. So EPROM wasn’t recognized by our instruments.<\/p>\n

Our idea was to try reconnecting the pin to the pad into the silicon circuit, applying two tiny wires. <\/p>\n

\"\"<\/p>\n

Result wasn’t good on this EPROM: we can read it but the content is blanked out, maybe for the current spike as a result of the wrong insertion. We think is completely damaged. <\/p>\n

\"\"<\/p>\n

So we tried this test on another purposefully damaged EPROM… and we had a success: we did the pin connection, EPROM was succesfully red and we also were able to reprogram it \ud83d\ude42 <\/p>\n

So we think this kind of data recovery from a burned EPROM is sometime profitable. \ud83d\ude42 <\/p>\n
