PROBLEM TO BE SOLVED: To surely analyze a dot pattern and sort the pattern even when there are many dots like a fault pattern on a semiconductor memory chip. SOLUTION: Coordinate counters SZ1 to SZ1024, ZZ1 to ZZ256 to respective coordinate values of coordinate axes are determined from the data of a dot pattern stored with a computer, the values of the counters SZ1 to SZ1024, ZZ1 to ZZ256 are formed from the detected number of dots and an input vector having a component formed from the counters SZ1 to SZ1024, ZZ1 to ZZ256 is inputted to a corresponding neuron circuit network. Thereby the neuron circuit network calcuates an output vector by comparing the input vector with a set vector based upon an example dot pattern and outputs the sort value of the dot pattern by the use of the found output vector. |
