    摘要： Multi-concentric pad (MCP) arrangements provide for increased pad densities on integrated circuits. The multi-concentric pad (MCP) configuration includes a first set of input output (IO) pads and a second set of IO pads, both disposed on an integrated circuit die. Each IO pad in said first set and said second set of IO pads includes a bond pad for receiving a bond wire connection, and an IO circuit coupled to the bond pad. The IO circuits provide an interface between a signal received at the corresponding bond pad and a core circuit disposed on said IC die. The first set of IO pads are arranged closer to the perimeter of the IC die than the second set of IO pads. Furthermore, the second set of IO pads are arranged so that each IO circuit in the second set of IO pads is closer to the center of the IC die than a corresponding IO circuit in the first set of IO pads.

    摘要： A computer system is disclosed comprising a host connected to a disk drive, the disk drive comprising a disk surface having a plurality of tracks arranged in an embedded servo format including servo track segments for storing servo data and data track segments for storing user data. The disk drive includes a read element operative during a user-data read operation for reading data from the disk surface to produce a time-multiplexed analog read signal that during a revolution of the disk represents analog read servo data during each of a first set of time intervals and represents analog read user data during each of a second set of time intervals. The disk drive includes a sampled signal processing circuit that generates a servo state variable while processing the time-multiplexed read signal during the first servo time interval and a user data state variable while processing the time-multiplexed read signal during the first user data time interval. The disk drive includes a servo state variable trap register for storing the servo state variable at the end of the first servo time interval. The disk drive includes a data state variable trap register for storing the user data state variable at the end of the first user data time interval. The disk drive includes a control circuit for providing the stored servo state variable to the sampled signal processing circuit at the beginning of the second servo time interval. The control circuit provides the stored user data state variable to the sampled signal processing circuit at the beginning of the second user data time interval.

    摘要： A state machine and an external interface, including its associated input-outputs (IOs), are always powered on and used to manage the chip power modes and power mode transitions. The chip power modes are defined as RUN, HIBERNATE, POWERDOWN, with many more possible with this invention. For example, once the device is in HIBERNATE or POWERDOWN modes, the power supplies to the IC are either reduced, or completely disconnected except for this controller state machine. This invention's state machine and control mechanism, in response to some external “wake up event”, will bring the chip to RUN mode by managing the state of the external power supplies through its control interface. The implementation achieves small die size and extreme low power consumption.
