Abstract: In a method of determining a critical temperature of a semiconductor package, heat is applied to at least one semiconductor package. Temperatures of the semiconductor package are measured during the heating. Heights of the semiconductor package are also measured during the heating. A temperature of the semiconductor package measured at a point at which a height from among the measured heights of the semiconductor package is sharply increased so that swelling of the semiconductor package occurs is determined as the critical temperature of the semiconductor package. Thus, the critical temperature of the semiconductor package may be accurately determined.

Abstract: A memory self-testing system, apparatus, and method are provided which allow for testing for a plurality of bit errors and passing memory arrays having an error level which is correctable using selected error correction coding. An exemplary system embodiment includes a memory array, a comparator, an integrator, and a test control circuit. The memory array is adapted to store input test data and output stored test data during a plurality of memory read and write test operations. The comparator compares the input test data and the stored test data for a plurality of bit positions, and provides a corresponding error signal when the stored test data is not identical to the input test data for each bit position of the plurality of bit positions. The integrator receives the corresponding error signal and maintains the corresponding error signal for each bit position during the plurality of test operations.

Abstract: A built-in, self-test (BIST) network employs a hierarchy of Universal BIST schedulers (UBSs) for scheduling and coordinating testing of elements, such as regular structure BISTed (RSB) elements and random logic BISTed (RLB) elements. Individual UBSs are preferably positioned in local areas, or sections, of an integrated circuit for testing of RSB and RLB elements within the local area. Testing of RSB and RLB elements within the local area allows the BIST network to minimize effects of delay and clock skew by employing relatively short interconnect routing between BISTed elements. Each of the individual UBSs are, in turn, controlled by a master UBS (MUBS) via simplified timing of control signals. The MUBS also may interface with an external testing device that initiates BISTed testing.

Abstract: A reconfiguration memory device is provided associated with a main memory array. The reconfiguration memory device generates a spare address in real time corresponding to a faulty address. The reconfiguration memory device is coupled to an address line, so that when address information is received for the main memory array, the address information is also received by the reconfiguration memory device. The reconfiguration memory device is adapted to send an output signal that results in the address in the spare memory address array being addressed, if the received address information corresponds to a stored faulty address. The output signal includes a spare control signal that directs components to look to the output of the spare memory.

Abstract: A method is provided for determining the location of faulty components in a computer memory array on a chip and for providing a software repair procedure. According to the method, the location of faulty components in a computer memory array is determined by successively reading and writing to locations in the array according to an algorithm. If a faulty component is detected, it is determined whether a spare component in a spare memory array on the chip is available. If a spare component is available, a spare component is designated to correspond to the faulty component. A look up table on the same chip stores information representing the location of the faulty component associated with information representing the location of the corresponding spare component.

Abstract: This invention relates to a token passing network, called a Universal BIST Scheduler (UBS), and a method for scheduling BISTed memory elements based on: executing BIST in multiple stages in order to optimize the efficiency of continuous processing and to apply a single waiting period to multiple SBRIC_RSs where, for example, BIST includes retention testing; dividing resource controllers or SBRIC_RSs corresponding to one or more RSB elements into a matrix such that each SBRIC_RS executes the BIST of its memory elements concurrently and/or successively depending on the SBRIC_RS's position in the matrix; and passing a token to initiate processing of a set of SBRIC_RSs in the matrix through a level signal rather than a pulse signal in order to ensure that the signal is not lost.

Abstract: A memory device has first and second sets of memory cells. Each of the cells in the second set is a neighboring cell corresponding to a respective cell of the first set. A data generating function generates a first pattern and a second pattern. A controller causes the first pattern to be written in the first set of memory cells, causes each cell in the second set of memory cells to be read simultaneously while the corresponding neighboring cell in the first set of memory cells is being written to, and causes a datum to be read from each cell in the second set of memory cells after the corresponding neighboring cell in the first set of memory cells is written to. An output data evaluator determines whether the data read from the second set of memory cells match the second pattern, and detects a fault in the memory device, if the data read do not match the second pattern.

Abstract: A method and apparatus are described for detecting an optimized set of predetermined faults in a memory device which ensure an acceptable quality level.
