Firmware is commonly stored in an EEPROM, which makes use of an I/O protocol such as SPI.
In computing, firmware is software that provides low-level control of computing device hardware.
For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality.
For a more complex device, firmware may provide relatively low-level control as well as hardware abstraction services to higher-level software such as an operating system.
Firmware is found in a wide-range of computing devices including personal computers, phones, home appliances, vehicles, computer peripherals and in many of the digital chips inside each of these larger systems.
Firmware is stored in non-volatile memory – either read-only memory (ROM) or programmable memory such as EPROM, EEPROM, or flash. Changing a device's firmware stored in ROM requires physically replacing the memory chip – although some chips are not designed to be removed after manufacture. Programmable firmware memory can be reprogrammed via a procedure sometimes called flashing.[1]
Common reasons for changing firmware include fixing bugs and adding features.
