摘要:
A memory card 100 having a NAND type flash memory connectable to a host device 200, capable of transmitting/receiving a signal to/from the host device 200 at a first voltage (3.3 V) or a second voltage (1.8 V) and safely changing a signal voltage of a transmission/reception signal that mutually checks a signal voltage through handshake processing with the host device 200 when the signal voltage is switched.
