Emulation of EEPROM for microcontrollers from the built-in flash memory2 years, 8 months ago
EEPROM — electrically the erased reprogrammable read-only memory which allows to write and rewrite data just as it occurs for normal disk storage modules. Flash is kind of EEPROM and is characterized by that record is made by blocks, and removal is carried out page-by-page. It is impossible to rewrite storage cell in arbitrary value on Flash. Memory like EEPROM usually allows to rewrite bigger number of times in comparison with Flash, but record on Flash is carried out for shorter time. In favor of Flash it is possible to add that this type of memory is cheaper in production, in comparison with EEPROM therefore devices in which EEPROM and (much relatively) memory Flash there is not enough at the moment prevail.
