Disclosed herein is a memory device capable of changing data output modes. According to the present invention, an address that is input to a circuit, which is designed in 8-bit output mode, is internally modified, to operate in 16-bit output mode, and a test operation is performed in 8-bit output mode. As such, two kinds of output mode circuits can be tested in one test equipment. Accordingly, test efficiency can be enhanced and costs can be saved.
