    Abstract: A method replaces a delay amount measurement in which an initially set value of a counter is determined by a technique which replaces measurement of a delay amount, whereby a time required for calibration of a delay circuit can be reduced. One counter set value of a plurality of counter set values is loaded, a delay lock loop circuit is switched to a lock mode, and a sequence circuit of a cycle slip detection circuit is reset. Thereafter, a cycle slip detection signal output from the sequence circuit is read, and on the basis of this cycle slip detection signal, it is judged whether or not an output signal of a delay circuit causes cycle slip. If the cycle slip is caused, the counter set value is switched. On the other hand, if any cycle slip is not caused, the counter set value is locked, thereby terminating the process.

    Abstract: A scan chain configuration and a control method for the same are provided, which are optimized for the leakage current reduction technique by a vector input in SoC in which many functional blocks are mounted. The semiconductor integrated circuit includes: plural power domains (Area1-AreaN) which have plural functional blocks; power switches (PSW1-PSWN) which can supply a power source for operation to the power domains; a scan chain provided for every power domain, and a memory unit (VEC) which supplies, to a scan chain, a vector to enable shifting to a low-leakage state. By re-coupling the scan chain only to a non-operating functional block, it is possible to perform shifting to a low-leakage state for a short time.

  • Patent number: 7525373
    Abstract: This invention relates to adaptively compensating for variations in integrated chip circuitry due to delays caused by multiple thresholds. The multi-threshold adaptive dynamic scaling system disclosed compensates for normal on-chip variations which affect system process and voltage variability, as well as overall performance. This system regulates a voltage control and provides high voltage thresholds, regular voltage thresholds, and low voltage thresholds to compensate for threshold voltage variations.

  • Publication number: 20090079496
    Abstract: Multi-chip package includes first through Nth semiconductor chips, each of which includes an input/output pad, an input/output driver coupled to the input/output pad, and an internal circuit. Each of the first through Nth semiconductor chips includes an internal pad for coupling the internal input/output driver and the internal circuit. The internal pads of the first through Nth semiconductor chips are coupled to each other such as via a common pad installed at a substrate. The input/output pad of the first semiconductor chip directly receives an input/output signal transmitted via a corresponding pin of the multi-chip package. The second through Nth semiconductor chips indirectly receive the input/output signal via the internal pads coupled to each other. The multi-chip package can improve signal compatibility by maintaining a parasitic load of a pin to at least the level of a single chip, when a signal is transmitted to the pin at high speed.

  • Patent number: 7486338
    Abstract: A TV tuner consisting of a least one low-noise amplifier, one mixer and one variable-gain amplifier plus two band-pass filters, the first of which is placed after low-noise amplifier and before the mixer, and the second of which is placed after mixer and before variable-gain amplifier. The filters are on-chip active devices equipped with on-chip frequency- and Q-tuning systems. The first band-pass filter is a real filter, such that its frequency response is symmetrical for positive and negative frequencies. The second band-pass filter is a complex filter, such that its frequency response has transmission for positive frequencies, but blocks negative frequencies. The low-noise amplifier includes gain control. The mixer is a complex-mixer consisting of two identical mixers driven by two local oscillator signals in quadrature.

  • Publication number: 20080204065
    Abstract: In a functional mode, the functional core logic of a die is connected to the input and output pads and the die performs its intended function. In a bypass mode, the input and output buffers of the functional core logic are disabled and pad sites of corresponding position between a first set of opposite sides and between a second set of opposite sides are electrically connected. In bypass mode the die is transformed into a simple interconnect structure between the first sides and between the second sides. The interconnect structure includes plural conductors extending substantially parallel to one another between the first sides and further plural conductors extending substantially parallel to one another between the second sides. While in bypass mode, signals from a tester apparatus can flow through the conductors between the first sides and between the second sides to access and test a selected die on a wafer.
