    摘要: A semiconductor memory device accessed with wordlines and bitlines has memory cells which operate at high performance with lower power consumption and have a high density. Each of the memory cells has pass transistors connected to a corresponding wordline and a corresponding pair of bitlines, and the pass transistors are gated by a signal of the corresponding wordline. The semiconductor memory device includes a wordline drive unit for selectively driving the wordlines in response to a row address. A wordline driver in the wordline drive unit boosts a corresponding wordline in a positive direction when the corresponding wordline is activated to access the memory cell and boosts the corresponding wordline in a negative direction when the corresponding wordline is inactive. By boosting the wordline in the positive direction, the performance of the memory cells is enhanced, and by boosting the wordline in the negative direction, a leakage current in the pass transistors with a low-threshold voltage is prevented.

    摘要: A power gate includes a series of electrical contacts along at least a portion of an integrated circuit and a series of power gate transistors electrically coupled to the electrical contacts on the integrated circuit to form a power gate boundary, e.g., at the integrated circuit periphery. The electrical contacts along at least a portion of a running length of the power gate boundary define a substantially non-linear profile. The non-linear profile provides increased contact density which improves current balancing across the electrical contacts and current throughput through the power gate. The non-linear profile is a sinusoidal or zigzag pattern with intermediate offset bump contacts. The contact profiles along the power gate boundary can include both linear and non-linear profiles.

    摘要: Power supply variations and jitter are measured by monitoring the performance of a ring oscillator on a cycle-by-cycle basis. Performance is measured by counting the number of stages of the ring oscillator that are traversed during the clock cycle and mapping the number of stages traversed to a particular voltage level. Counters are used to count the number of ring oscillator revolutions and latches are used to latch the state of the ring oscillator at the end of the cycle. Based on the counters and latches, a monitor output is generated that may also incorporate an adjustment for a reset delay associated with initializing the ring oscillator and counters to a known state.

    摘要: A detector circuit and method for detecting a silicon well voltage or current to indicate an alpha particle or cosmic ray strike of the silicon well. One significant application for the detection circuit of the present invention is for the redundancy repair latches that are used in SRAMs. The redundancy repair latches are normally written once at power-up to record failed latch data and are not normally written again. If one of the latches changes states due to an SER (Soft Error Rate-such as a strike by an alpha particle or cosmic ray) event, the repair data in the redundancy latches of the SRAM would now be incorrectly mapped. The detector circuit and method monitors the latches for the occurrence of an SER event, and responsive thereto issues a reload of the repair data to the redundancy repair latches. A first embodiment of the detector circuit differentially detects the floating voltages of first and second silicon wells during periods of non-operation of the circuits fabricated in the first and second silicon wells. In a second embodiment, a detector circuit monitors the background voltage level of a single silicon well over first and second consecutive periods of time. A second application for the detection circuit is for traditional logic circuits.
