NONVOLATILE MEMORY CARD BY AUTOMATIC POWER SUPPLY CONFIGURATION

摘要

PURPOSE: To obtain a memory card which can be used by a computer of a different power source voltage. CONSTITUTION: Plural memories 12 and 13 are provided with circuits receiving a device power source voltage display signal displaying the voltage level of the power source voltage of the the device and operating corresponding to the voltage level of the power source voltage of the device. In order to generate the device power source voltage display signal by detecting the voltage level of the power source voltage of the device, a voltage detection circuit 60 is combined to the input of the power source.
