Abstract: A latch-up protection circuit for an integrated circuit using complementary MOS circuit technology has a substrate bias generator that applies a negative substrate bias to a semiconductor substrate having a p-conductive material into which a well-shaped semiconductor zone of n-conductive material is inserted. In order to avoid latch-up effects in the integrated circuit, an electronic protection circuit interrupts the capacitive charging currents of a capacitor in the substrate depending on the potential of the semiconductor substrate which is taken at a doped substrate bias terminal. The electronic protection circuit connects a capacitor bias generator to the capacitor when a voltage on the substrate bias terminal is less than a sum of a reference potential and a threshold voltage of a first transistor in the electronic protection circuit. The electronic protection circuit disconnects the capacitive bias generator from the capacitor when a voltage on the substrate bias terminal is greater than the sum. During normal operation the electronic protection circuit does not load a supply voltage source or a substrate bias voltage source with current.

Abstract: A digital data processing apparatus utilizes a common bus structure (42, 44, 46) for transferring information between functional units, including a processing unit (12), a peripheral control unit (20), and first and second memory units (16, 18). Unit-to-unit information transfers are executed on the bus structure by transferring signals representative of a transfer cycle that occurs during plural timing intervals and includes plural phases, including a definition phase, a response phase, and a data-transfer phase, where the phases of one cycle are non-overlapping and occur in sequence in different respective timing intervals of the transfer cycle. The functional units are arranged for pipelining transfer cycles by transferring concurrently on the bus structure signals representative of differing phases of plural cycles. A signalling element periodically generates a first signal indicative of the necessity to refresh at least one dynamic memory element in the first memory unit. A memory refresh element normally responds to that first signal for executing a memory refresh cycle during at least one timing interval common to first and second pipelined transfer cycles. A signal is generated indicating the onset of the memory refresh cycle. A memory update element can respond to the first signal by initiating execution of a memory update cycle for transferring information from the first memory unit to the second memory unit during a timing interval common to first and second pipelined transfer cycles. The update element generates a signal indicating of the onset of the update cycle. The data processing apparatus includes a pipeline element which responds to the aforementioned onset signals for aborting further execution of said first transfer cycle while continuing the execution of said second transfer cycle.

Abstract: The present invention covers a semiconductor wafer for semi-custom use in which there are no scribe lines in at least one direction. Electrically isolated cells are provided throughout the wafer. The scribe lines can thus be arbitrarily placed according to an individual customer's instructions, with the isolated cells near the scribe line being covered with metalization to form a bonding pad. Preferably, scribe lines are provided in one direction, either horizontal or vertical. This allows fixed bonding pads to be placed near these scribe lines and allows special components, such as power transistors and ESD protection systems to be placed near the fixed bonding pads. This provides better silicon efficiency than the embodiment with no fixed scribe lines by simplifying the routing. The components which need to be near the bonding pads are placed there, rather than being located randomly throughout the wafer. The customer can then specify a length of a cell which has a fixed height.
