A semiconductor testing device includes: a data memory which stores a test program, said test program generating a test command for testing a plurality of functions within one function area of a plurality of function areas of a semiconductor device, said test command being generated for said function area; a first area generation part which generates first data, said first data identifying one function area of said plurality of function areas, said plurality of functions of said one function area being tested; a main control part which generates said test command based on said test program and said first data and transmits said test command to said semiconductor device; a second area generation part which receives a first result, said first result being returned from said semiconductor device based on a first test in accordance with said test command and generates a second result based on said first result, said second result showing a pass or failure of said first test corresponding to said function area; and a third area generation part which generates second data based on said second result and transmits said second data to said first area generation part, said first area generation part generating third data based on said second data, said third data identifying one or more of said plurality of function areas, said one or more of said plurality of function areas being the object of a second test subsequent to said first test.
