Serial flash memory evolution infographic

The Changing Serial Flash Memory LandscapeSPI [pronounced "S.P.I" or "spy]The serial peripheral interface (SPI) is an interface that enables theserial (one bit at a time) exchange of data between two devices.It has been employed in systems for communication betweenprocessors and Flash memory. The simple serial interfacerequires fewer connections and thus fewer pins. This lowers cost,simplifies board layout and reduces the form factor of manyembedded designs.
