  • Patent number: 6381184
    Abstract: A circuit transfers data in an array of memory cells arranged in rows and columns. The circuit includes a plurality of row lines, a plurality of pairs of complementary digit lines, and an array of memory cells, each memory cell having a control terminal coupled to one of the row lines and a data terminal coupled to one of the complementary digit lines of one of the pairs of complementary digit lines responsive to a row enable signal on the row line of the row corresponding to the memory cell. A plurality of sense amplifiers are included in the circuit, each sense amplifier coupled to an associated pair of first and second complementary digit lines which senses a voltage differential between the first and second complementary digit lines and, in response to the sensed voltage differential, drives the first and second complementary digit lines to voltage levels corresponding to complementary logic states.

  • Patent number: 6356474
    Abstract: A memory device has an open-array architecture that includes alternate digit lines in the end subarrays that are not normally coupled to a sense amplifier. These digit lines are not normally coupled to a sense amplifier because there is no adjacent subarray containing digit lines that could be coupled to the other input of the sense amplifier. A sense amplifier is provided for each of these normally unused digit lines, and each normally unused digit line is coupled to one of the imports of a respective sense amplifier. The other input of each sense amplifier is coupled to a dummy load that is provided to simulate the resistance and capacitance of an actual digit line. The dummy load has a capacitance that may be adjusted so that the capacitance at both inputs to each sense amplifier are substantially equal. As a result, normally unused digit lines in the end subarray of a memory array, as well as the memory cells coupled to the digit lines, may be used.

  • Publication number: 20020027278
    Abstract: The formation of routing traces on an external surface of a semiconductor device, such as a flip-chip, which has a plurality of ball or bump sites patterned in specific locations, wherein the ball or bump sites are in electrical communication with external communication traces which are used to route signals from the flip-chip integrated circuitry. Such external communication traces generally result in unused space on the exterior surface of the flip-chip. This unused space can be utilized for forming routing traces to connect portions of the internal circuitry of the flip-chip rather than forming such routing traces internally, for forming routing traces to connect two or more semiconductor dice, or for forming routing traces for use as repair mechanisms.

  • Patent number: 6326245
    Abstract: Logic circuitry formed in street areas between adjacent fabricated electronic devices may be used as auxiliary or redundant components to salvage one or more otherwise defective devices. Logic circuitry is selectively coupled to the defective device(s) to directly replace or facilitate the replacement of defective components on one or more fabricated devices, thereby resulting in a single operable electronic device. The invention may be used to increase the production yield of electronic devices, particularly, semiconductor integrated circuits. The invention permits the fabrication of discretionary wiring during the normal metalization of semiconductor layers to interconnect electronic devices at the same time as the formation of the normal wiring/circuitry of the devices.

  • Publication number: 20010009029
    Abstract: An IC module, such as a Multi-Chip Module (MCM), includes multiple IC dice, each having a test mode enable bond pad, such as an output enable pad. A fuse incorporated into the MCM's substrate connects each die's test mode enable bond pad to one of the MCM's no-connection (N/C) pins, and a resistor incorporated into the substrate connects the test mode enable bond pads to one of the MCM's ground pins. By applying a supply voltage to the test mode enable bond pads through the N/C pin, a test mode is initiated in the dice. Once testing is complete, the fuse may be blown, and a ground voltage applied to the test mode enable bond pads through the ground pins so the resistor disables the test mode in the dice and initiates an operational mode. As a result, dice packaged in IC modules may be tested after packaging.

  • Patent number: 6229296
    Abstract: A circuit for reading and forcing a voltage at a node of an integrated circuit. In one embodiment, the circuit comprises a pass element that has an output that is coupled to a pin of the integrated circuit. A reset circuit is coupled to the pass circuit and is operable to activate and reset the pass circuit. Finally, a pass control circuit is coupled to provide a signal to the pass circuit that drives the pass circuit when active to pass the voltage at the node to the pin. In one embodiment, the circuit further includes a scaler circuit that establishes a ratio between the voltage at the node and the voltage at the pin such that high voltages can be passed to or from the node by the pass element.

  • Patent number: 6230292
    Abstract: Methods for testing semiconductor memory devices are performed during the writing and reading of test information to and from memory cells. During the tests, operational parameters such as commencement of timing signals and the voltage levels thereof which are employed to activate components of a memory device are controllably adjusted in an effort to intentionally imbalance or alter the voltage differential appearing on the bit lines. If the memory device has a defect, the voltage levels on the bit lines are altered to such a degree that the sense amplifier, although properly sensing the voltage differential, incorrectly senses the intended test information stored in the memory cells. As the parameters are manipulated, the test information written from the memory cell and error signals are generated when the information is not the same. Circuitry for performing methods for testing semiconductor memory devices during the writing and reading of test information to and from memory cells is also disclosed.
