    摘要: A circuit for isolating a short-circuited integrated circuit (IC) formed on the surface of a semiconductor wafer from other ICs formed on the wafer that are interconnected with the short-circuited IC includes control circuitry within the short-circuited IC for sensing the short circuit. The control circuitry may sense the short circuit in a variety of ways, including sensing excessive current drawn by the short-circuited IC, and sensing an abnormally low or high voltage within the short-circuited IC. Switching circuitry also within the short-circuited IC selectively isolates the short-circuited IC from the other ICs on the wafer in response to the control circuitry sensing the short circuit. As a result, if the wafer is under probe test, for example, testing can continue uninterrupted on the other ICs while the short-circuited IC is isolated.

    摘要: A semiconductor wafer having dice that include circuitry that is placed into a mode when the circuitry receives an alternating signal having certain characteristics. The alternating signal may be supplied from a system controller through a probe, probe pad, and conductive path on the wafer. In a preferred embodiment, the conductive path simultaneously carries a VCC power signal and the alternating signal to the circuitry. However, the alternating signal may be carried on a conductive path different from the one carrying the VCC signal. A great deal of information may be conveyed through the alternating signal, making other signals unnecessary in controlling, testing, stressing, and repairing dice on the wafer. For example, clocking information may be conveyed through the alternating signal. The circuitry may be placed in different modes in response to different characteristics of the alternating signal. The alternating signal and a VCC power signal are received through a single contact on each die. A wafer mode controlling system includes a system controller to control application of the alternating signals and other signals to the dice on the wafer. The semiconductor wafer mode controlling system may also control a probe positioning controller including an array of probes that selectively brings the probes into contact with the probe pads, whereby the alternating signal having the certain characteristics is transmitted from the probe to the circuitry through the probe pad and conductive path and the circuitry of each of the dice is placed into the mode.

    摘要: A method for sorting integrated circuit (IC) devices of the type having a fuse identification (ID) into those devices requiring enhanced reliability testing and those requiring standard testing includes storing fabrication deviation data, probe data, and test data in association with the fuse ID of each of the devices indicating each of the devices requires either enhanced reliability testing or standard testing. The fuse ID of each of the devices is then automatically read before, during, or after standard testing of the devices. The testing process requirement data stored in association with the fuse ID of each of the devices is then accessed, and the devices are sorted in accordance with the accessed data into those devices requiring enhanced reliability testing and those requiring standard testing. The method thus directs those devices needing enhanced reliability testing to such testing without the need for all devices from the same wafer or wafer lot to proceed through special testing.

    摘要: A 256 Meg dynamic random access memory is comprised of a plurality of cells organized into individual arrays, with the arrays being organized into 32 Meg array blocks, which are organized into 64 Meg quadrants. Sense amplifiers are positioned between adjacent rows in the individual arrays while row decoders are positioned between adjacent columns in the individual arrays. In certain of the gap cells, multiplexers are provided to transfer signals from I/O lines to data lines. A datapath is provided which, in addition to the foregoing, includes array I/O blocks, responsive to the datalines from each quadrant to output data to a data read mux, data buffers, and data driver pads. The write data path includes a data in buffer and data write muxes for providing data to the array I/O blocks. A power bus is provided which minimizes routing of externally supplied voltages, completely rings each of the array blocks, and provides gridded power distribution within each of the array blocks. A plurality of voltage supplies provide the voltages needed in the array and in the peripheral circuits. The power supplies are organized to match their power output to the power demand and to maintain a desired ratio of power production capability and decoupling capacitance. A powerup sequence circuit is provided to control the powerup of the chip. Redundant rows and columns are provided as is the circuitry necessary to logically replace defective rows and columns with operational rows and columns. Circuitry is also provided on chip to support various types of test modes.

    摘要: An inventive method for sorting integrated circuit (IC) devices of the type having a substantially unique identification (ID) code, such as a fuse ID, includes automatically reading the ID code of each of the IC devices and sorting the IC devices in accordance with their automatically read ID codes. The inventive method can be used in conjunction with an IC manufacturing process that includes providing semiconductor wafers, fabricating the IC's on each of the wafers, causing each of the IC's to store its ID code, separating each of the IC's from its wafer to form IC dice, assembling the IC dice into IC devices, and testing the IC devices. The inventive method is useful for, among other things, culling IC reject bins for shippable IC's, sorting IC's from a wafer lot into those that require enhanced reliability testing and those that do not, and allowing IC's fabricated using both a control fabrication process recipe and a new fabrication process recipe under test to be assembled and tested using the same equipment to reduce unintended test variables introduced when the IC's are assembled and tested separately.
