    Abstract: A circuit, apparatus and method obtains system margin at the receive circuit using phase shifted data sampling clocks while allowing the CDR to remain synchronized with the incoming data stream in embodiments. In an embodiment, a circuit includes first and second samplers to sample a data signal and output data and edge information in response to a data clock signal and an edge clock signal. A phase detector generates phase information in response to the data information and the edge information. A clock phase adjustment circuit generates the data clock signal and the edge clock signal in response to the data information during a synchronization mode. The clock phase adjustment circuit increments a phase of the data clock signal during a waveform capture mode.

    Abstract: At page 54, please delete the current abstract and replace it with the following: An integrated circuit memory device comprises a latch circuit to load an address using a first control signal. A first signal level transition of the first control signal is used to load the address. A memory array stores data at a memory location that is based on the address. An output buffer outputs the data after a period of time from the first signal level transition. A register stores a value that specifies between at least a first mode and a second mode. When the value specifies the first mode, the output buffer outputs the data in response to address transitions that occur after the first signal level transition. When the value specifies the second mode, the output buffer outputs data synchronously with respect to an external clock signal.

    Abstract: A technique for receiving differential multi-PAM signals is disclosed. In one particular exemplary embodiment, the technique may be realized as a differential multi-PAM extractor circuit. In this particular exemplary embodiment, the differential multi-PAM extractor circuit comprises an upper LSB sampler circuit configured to receive a differential multi-PAM input signal and a first differential reference signal, and to generate a first differential sampled output signal. The differential multi-PAM extractor circuit also comprises a lower LSB sampler circuit configured to receive the differential multi-PAM input signal and a second differential reference signal, and to generate a second differential sampled output signal. The differential multi-PAM extractor circuit further comprises a combiner circuit configured to receive the first differential sampled output signal and the second differential sampled output signal, and to generate a differential LSB output signal indicating an LSB value of the differential multi-PAM input signal.

    Abstract: The present invention includes a memory subsystem comprising at least two semiconductor devices, including at least one memory device, connected to a bus, where the bus includes a plurality of bus lines for carrying substantially all address, data and control information needed by said memory devices, where the control information includes device-select information and the bus has substantially fewer bus lines than the number of bits in a single address, and the bus carries device-select information without the need for separate device-select lines connected directly to individual devices. The present invention also includes a protocol for master and slave devices to communicate on the bus and for registers in each device to differentiate each device and allow bus requests to be directed to a single or to all devices. The present invention includes modifications to prior-art devices to allow them to implement the new features of this invention. In a preferred implementation, 8 bus data lines and an AddressValid bus line carry address, data and control information for memory addresses up to 40 bits wide.
