  • Patent number: 5633828
    Abstract: According to the present invention, a structure and method provides for single bit failures of an integrated circuit memory device to be analyzed. According to the method for analyzing a single bit failure of an integrated circuit memory device, a test mode is entered, bitline load devices of the integrated circuit memory device are turned off, a single bit of the integrated circuit memory device is selected, the device is placed into a write mode, a plurality of bitlines true and a plurality of bitlines complement of the integrated circuit memory device not associated with the single bit are then set to a low logic level, the bitline true and the bitline complement associated with the single bit is connected to a supply bus and a supply complement bus which is connected to test pads. Finally, the electrical characteristics of the single bit can be monitored on the test pads.
