What type of flash memory is used in this Snes cartridge to store the OS and what is the data retention time on that memory?
Data retention is on the order of 10-20 years. Have you checked datasheets for the parts used?these images are from my board it is the same but i don't know how to flash this hardware and data retention stored unused for long periods
I didn't bother to try to get part numbers from the pictures. NOR would be more reliable than NAND, particularly MLC. The 10 years isn't exact. Programmed cells will lose electrons over time. The rate depends on things like temperature and the quality of the gate oxide.this flash memory on the board is NOR flash? is data lost after 10 years inevitable?
The datasheet specifies a minimum data retention period of 20 years.memory flash m29w640ft 70n6 h
It's a NOR flash and 20 years isn't an exact retention period; it's the minimum.after 20 years of storage data is inevitably lost from this NAND flash?
