Abstract This invention is associated with a memory card apparatus using EEPROMs (19) as semiconductor memories. Externally input date are temporarily recorded in a buffer memory (13) and are subsequently written in the EEPROMs (19). Verify processing is automatically performed between the buffer memory (13) and the EEPROMs (19). Similarly, data read out from the EEPROMs (19) are temporarily recorded in the buffer memory (13) and are subsequently output to an external unit. Even with the EEPROMs (19), it seems that this memory card can be used in the same manner as a memory card using an SRAM, when viewed from the outside of the card.
