    摘要: Embodiments of the invention are related to sense amplifiers. In an embodiment involving a sense amplifier used with a memory cell, signals BL, ZBL, SN and SP are pre-charged and equalized to a voltage reference, e.g., Vref, using an equalizing signal. A compensation signal, e.g., SAC, is applied to compensate for the mismatch between transistors in the sense amplifier. The word line WL is activated to connect the memory cell to a bit line, e.g., bit line ZBL. Because the memory cell shares the charge with the connected bit line ZBL, it causes a differential signal to be developed between bit lines BL and ZBL. When enough split between bit lines BL and ZBL is developed, signals SP and SAE are raised to VDD (while signal SN has been lowered to VSS) to turn on the sense amplifier and allow it to function as desire. Other embodiments and exemplary applications are also disclosed.

    摘要: As technology scales, on-chip interconnects are becoming narrower, and the height of such interconnects is not scaling linearly with the width. This leads to an increase of coupling capacitance with neighboring wires, leading to higher crosstalk. It also leads to poor performance due to poor RC response at the receiving of the wire, which may even result in failure in very noisy environments. An adaptive threshold scheme is proposed in which receiver switching thresholds are adjusted according to the detected noise in bus lines. These noise levels are dependent on both the front-end processing (transistor performance) as well as on the backend processing (metal resistance, capacitance, width and spacing). The circuit therefore automatically compensates for process variations.

    摘要: An integrated circuit (300) has a regular grid formed by substantially identical building blocks (100a-i). To avoid possible routing conflicts around the edges of the integrated circuit (300), which can be introduced by the use of a single type of an asymmetric building block, the integrated circuit (300) is extended with routing cells (200) that provide routing at the edges of the grid that are uncovered by the routing networks of the building blocks (100a-i). The routing cells (200) and the switch cell (250) are combined with a first routing structure (330) and a second routing structure (340) to form a routing network (280) surrounding the grid of the integrated circuit (300). Consequently, an integrated circuit (300) is presented that comprises only a single type of building block (100a-i) but still has a fully symmetric routing architecture.

    摘要: A buffer circuit (31), for example a repeater or receiver circuit for a signal wire of an on-chip bus, receives an input signal, and produces an output signal. The buffer circuit (31) comprises a first inverting stage (7) and a second inverter stage (9). The second inverting stage (9) provides the drive for the output (5). The first inverting stage (7) has additional circuitry (15, 17, 19, 21, 23, 25, 27, 29) for controlling the strengths of the pull up path and the pull down path. The pull up/down paths are dynamically controlled according to the status of one or more aggressor signals. In one embodiment the switching threshold is lowered only in the worst case delay scenario, i.e. when the signal wire (3) is at a different logic level to the aggressor signals. In another embodiment, the switching threshold is raised when the signal wire and aggressor signals are all at the same logic level, thereby reducing crosstalk.

    摘要: A clamper circuit (1) receives an input signal (3) from the signal wire being clamped, i.e. the victim wire. The clamper circuit (1) also receives aggressor signals (5, 7) from aggressor wires, the aggressor wires being the signal wires that can potentially induce crosstalk on the victim wire. An output signal (9), for clamping the victim wire, is selectively enabled based on the logic states of the input signal (3) and the aggressor signals (5, 7). In addition to selectively providing a clamping signal, the clamper circuit (1) also has the advantage of accelerating the switching of the victim wire when an opposite transition occurs on the aggressors and victim wire at the same time, thereby reducing worst case delay and improving the signal integrity.

    摘要: An electronic data processing circuit uses current mode signalling on a communication conductor, wherein a receiver supplies current to the communication conductor to try and keep a voltage on the conductor constant and measures the current that is needed to do so. A transition coding circuit is coupled between a data source circuit and the communication conductor, for driving the communication conductor in a first state in pulses in response to transitions in the logic signal and in a second state outside the pulses. The level that is used for indicating no change is selected so the current that needs to be supplied by the receiver is smaller when no change is signalled than when a change is signalled. Preferably only a nearly zero quiescent current is needed when there is no change.
