ABSTRACT:
Semiconductor memory devices are tested by using a special purpose computer which uses simple test patterns to determine the weakest bits of the device and then tests only these relatively few "weak bits" and structurally and operationally adjacent bits using highly complex test patterns to determine if the device is functioning properly. This procedure considerably reduces testing time over that required using prior art techniques.
