Abstract: A simulation SmartMedia/xD-Picture memory card capable of using various kinds of non-volatile memory has at least one non-volatile memory chip for storing data; a card interface and a controller. The card interface is defined with command, data and address signal for enabling an external host computer to access the data in the non-volatile memory chip. The controller is used for interpreting a command sent from the host computer and changing an address sent from the host computer to a valid address for the non-volatile memory chip to go to the non-volatile memory chip to write, read or delete the data.
