  • Publication number: 20130155752
    Abstract: Devices and circuits for wiring configurations of a bus system and power supply wires in a memory chip with improved power efficiencies. For example, the effective resistance on the power supply wires can be reduced by utilizing non-active bus wires as additional power wires connected in parallel with the other supply wires. Further, these non-active bus wires can reduce or prevent parasitic couplings and cross-talk effects between neighboring sensitive wires, thereby improving the performance of the chip.

  • Publication number: 20120229203
    Abstract: A multi-fingered device can be calibrated for performance. The multi-fingered device can include a first finger configured to remain active and a second finger that is initially deactivated concurrent with the first finger being active. A measure of degradation for the multi-fingered device within an IC can be determined. The measure of degradation can be compared with a degradation threshold. Responsive to determining that the measure of degradation meets the degradation threshold, a finger of the multi-fingered device can be activated.

  • Patent number: 8035424
    Abstract: An AC-coupled interface circuit on a semiconductor integrated circuit apparatus performing a bidirectional data transfer via a differential transmission line includes a differential driver, a differential receiver and a potential setting section. The differential driver includes a pair of output terminals connected to a pair of signal lines. The differential receiver includes a pair of input terminals connected to the pair of signal lines. In a data transmission operation, the differential driver converts transmit data to a differential signal to output the differential signal. In a data reception operation, the differential receiver receives a differential signal transferred to the pair of signal lines and converts the differential signal to receive data. The potential setting section sets a potential of the pair of signal lines to a predetermined stable potential before the differential signal is transferred to the pair of signal lines.

  • Patent number: 6946904
    Abstract: A transceiver circuit includes driver circuits, receiver circuits, and suspend-mode buffers that are arranged to withstand an over-voltage conditions that would otherwise damage those circuits. An over-voltage sense circuit is arranged to detect the over-voltage condition on a data line in the transceiver. Cascode devices are placed in critical points of the various circuits, while voltages are coupled to other critical points such that none of the transistor devices that are coupled to the data lines are damaged by the over-voltage condition. Selector circuits are arranged to couple the highest detected voltages to various transistor wells to prevent forward biasing parasitic diodes in the transistors. Series switching circuits are arranged to break critical conduction paths during the over-voltage condition. The over-voltage protection scheme is suitable for use in integrated USB transceivers.
