what are the most uses for each serial and parallel flash memories ? specially their functions on boards
Those devices are writeable onboard like e.g. RAM but keep their contents even without being powered. Therefore these devices are also often called 'non-volatile' memory devices, or NVRAM. MUses are the storage of e.g. MAC Adresses on network cards (you'll find one on every network card), parameters or data which are unique for a unit but need to be stored permanently like calibration data.

Parallel devices can be used like conventional memory at least when reading, e.g. they can be used as program memory. Georg
thanks , that was really helpfull
