Flash memory is a long-term dynamic non-volatile memory that can be deleted and adapted in a storage unit called block. Flash memory is a variant of the electrically erasable read-only memory (EEPROM), which differs from flash memory in that it can be deleted and rewritten at the byte level so that the EEPROM is slower to update than Flash. Flash memory is often used to hold control code, USB Flash Drive such as a basic input-output system (BISO) in a personal computer. When the BIOS needs to be changed (rewritten), the flash memory can be written to block (not byte) size, making it easier to update. Flash memory, on the other hand, is not as useful as any access memory (RAM), because any access memory must be at the byte (not block) level where the address is settable.
