ABSTRACT:
An apparatus for recognizing the state of connection of terminals by recognizing the connection state of a plurality of terminals of a memory device including a non-volatile memory unit, such as a flash memory, comprises a data storage unit disposed inside the memory device, for storing connection state recognition data necessary for recognizing a connection state of a plurality of terminals of the memory device including the non-volatile memory unit, disposed inside the memory device; a switching control unit having the function of switching the current state to the state for outputting the connection state recognition data between the non-volatile memory unit and the data storage unit; and a data detecting unit for detecting the connection state recognition data outputted from the switching control unit, and confirming whether or not there is any connection fault of a plurality of terminals on the basis of the connection state recognition data which is detected by the data detecting unit. A method for recognizing the state of connection of terminals, in which the connection fault of a plurality of terminals of a memory device is detected by using the connection state recognizing apparatus described above, is also disclosed.
