nogueiraat Posted May 8, 2021 Report Share Posted May 8, 2021 manufacturers of NOR flash memory chips say that they retain data for up to 20 years but I am doubtful if it is possible to increase this retention estimate a lot? I write the firmware only once in the flash memory and store it I don't want to lose retention Quote Link to comment Share on other sites More sharing options...
HarryA Posted May 9, 2021 Report Share Posted May 9, 2021 The problem is what will read a flash drive 20 years from now? The same for data storage devices like CD's, hard drives, and tapes. Perhaps the best solution is to transfer the data to new media every few years. Also it is a good idea to store copies off site (at friend's home for example) in case a Chinese spent rocket lands on your house. Or print on papyrus and seal in clay jars 😀 Quote Link to comment Share on other sites More sharing options...

nogueiraat Posted May 23, 2021 Author Report Share Posted May 23, 2021 In NOR flash memory the data loss happens 20 years after the data recorded on the chip or not? it is possible to extend the retention above 20 years for the NOR M29W640FT 70N6 H flash memory Quote Link to comment Share on other sites More sharing options...
