Abstract
An IC memory card (11) has a mode change switch (18) for switching operation modes of a semiconductor component in the vicinity of an end side opposite the external connection terminals (17a to 17i). A controller LSI (24) detects the status of the mode change switch (18) and switches operation modes according to the detected status.
