In fact, for users, the main difference between EEPROM and FLASH is

1. EEPROM can be erased by "bit", while FLASH can only erase large pieces one by one.

2. EEPROM generally has a small capacity, and if it is large, EEPROM does not have a price advantage compared to FLASH. The standalone EERPOM sold on the market is generally below 64KBIT, while FLASH is generally above 8MEG BIT (NOR type).

3. In terms of reading speed, it shouldn't be the difference between the two, it's just that EERPOM is generally used for low-end products, and the reading speed doesn't need to be so fast. If you really want to do it, it can actually be made similar to FLASH.

4. Because the storage unit of EEPROM is two tubes and FLASH is one (except for SST, which is similar to two tubes), CYCLING's EEPROM is better than FLASH, and there is no problem even after 1000K cycles.

Overall, there is no significant difference between EEPROM and FLASH for users, except that EEPROM is a low-end product with lower capacity and cheaper price, but its stability is better than FLASH. But for the design of EEPROM and FLASH, FLASH is much more difficult, both in terms of process and peripheral circuit design.
