  • SEMICONDUCTOR MEMORY CARD, METHOD FOR CONTROLLING THE SAME, AND SEMICONDUCTOR MEMORY SYSTEM
    Publication number: 20150378813
    Abstract: A semiconductor memory card which can be attached to a host apparatus and can be removed from the host apparatus includes a plurality of data transfer terminals, and an internal circuit transmitting a first signal to at least one first data transfer terminal comprising at least one of the data transfer terminals and transmitting a second signal to at least one second data transfer terminal comprising at least one of the data transfer terminals different from the first data transfer terminals. The second signal is generated by executing a logical operation on the first signal.
