    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: An architecture for a high-capacity high-speed semiconductor memory device is disclosed. The semiconductor memory device includes memory cell arrays (406) having local word lines and bit lines. The memory cell arrays (406) are further arranged into array groups (402a-402d and 404a-404d). The local word lines (410a-410d) of the memory cell arrays of the same group are commonly connected to global word lines (408). The array groups (402a-402d and 404a-404d) provide data access paths to their respective memory cells by sets of input/output (I/O) lines (416a-416d and 420a-420d). The I/O line sets (416a-416d and 420a-420d) are coupled to data amplifiers by interarray multiplexers (MUXs) (422a-422d). The interarray MUXs (422a-422d) enable defective global word lines of one array group to be replaced by redundant global word lines of an adjacent array group.

    摘要: An integrated circuit (IC) architecture includes a bit mask register (BMR) and a serial access memory (SAM) which share address decode and clock circuitry within a multiport random access memory chip. The integrated circuit also includes a random access memory and circuitry for performing a bit masked transfer between the serial access memory and the random access memory. Mask data may be clocked into the bit mask register, which may be cleared upon completion of a data transfer between the random access memory and the serial access memory. The mask data may also be inverted upon being transferred between the random access memory and the bit mask register. This architecture provides CLEAR and TRUE or COMPLEMENT masked transfer output ability in the BMR, and has utility in real-time video windowing in memory mapped computer graphics.

    摘要: Presented is an integrated circuit chip including a random access memory (RAM) array, serial access memory (SAM), an arithmetic logic unit, a bidirectional shift register, and masking circuitry. The arithmetic logic unit, SAM, shift register, and masking circuitry are all as wide as one side of the RAM array, and are all communicable with each other via data transfer means. This allows wide word processing, user configurable for parallel processing. Bits masked by the masking circuitry are selectable by data in the bidirectional shift register, providing shiftable masking means. Random access and serial access are done through separate ports. The bidirectional shift register is optionally serially accessible. Methods of use are also presented.

    摘要: A memory integrated circuit chip of a predefined circuit topology has an on-chip topology logic driver. The topology logic driver selectively inverts data being written to and read from addressed memory cells in the memory IC based upon location of the addressed memory cells in the circuit topology of the memory array. The topology logic driver is preferably a logic circuit that embodies a boolean function defining the circuit topology. A method for testing and producing such memory ICs is also described.

    摘要: The invention is the circuit and method for selecting a window of desired address locations to be written. A start address and a stop address activate a start and stop decoder output respectively. The active start and stop decoder output signals are rippled through start and stop ripple circuitry which enables the outputs electrically interposed between the start and stop addresses respectively. AND circuitry ensures that only the outputs interposed between the start and stop addresses are activated in addition to the start and stop decoder outputs. The activated outputs comprise the window of desired address locations to be written.
