摘要： A memory device including a memory array storing data, a variable delay controller, a passive variable delay circuit and an output driver. The variable delay controller periodically receives delay commands from a first source external to the memory device during operation of the memory device, and outputs delay instruction bits responsive to the received delay commands. The passive variable delay circuit receives a clock from a second source external to the memory device, receives the delay instruction bits from the variable delay controller, generates a delayed clock having a time relation to the received clock as determined by the delay instruction bits, and outputting the delayed clock. The output driver receives the data from the memory array and the delayed clock, and outputs the data at a time responsive to the delayed clock.

摘要： An embodiment of the invention comprises a digital phase detector with substantially zero phase offset. The digital phase detector receives a clock signal and a reference clock signal and provides a phase indicator signal to identify whether the clock signal leads or lags the reference clock signal. An embodiment of the invention comprises a method that adds substantially zero phase offset in processing an input clock signal and a delayed clock signal to generate a control signal. The control signal is processed in a variable delay line to generate the delayed clock signal. In an embodiment, a first processor comprises a delay locked loop having a digital phase detector, the digital phase detector comprising a first differential sense amplifier cross-coupled to a second differential sense amplifier, the digital phase detector receiving a clock signal and generating one or more delayed clock signals, a control signal, and a gated data signal.

摘要： A multi-use physical (PHY) architecture that includes a PHY connection that includes one or more bit lines and that is communicatively coupled to a first processor. The PHY connection is configurable to carry signals between the first processor and a second processor, or between the first processor and a memory. The one or more bit lines are configured to carry signals bi-directionally at a first voltage when the PHY connection is configured to carry signals between the first processor and the memory. The one or more bit lines are configured to carry signals uni-directionally at a second voltage when the PHY connection is configured to carry signals between the first processor and the second processor. The second voltage is different than the first voltage.

摘要： A method and apparatus for determining correct timing for receiving, in a host in a memory system, of a normal toggle transmitted by an addressed memory chip on a bidirectional data strobe. An offset in the data strobe is established, either by commanding the addressed memory chip, in a training period, to drive the data strobe to a known state, except during transmission of a normal toggle, or by providing a voltage offset between a true and a complement phase in the data strobe, or by providing a circuit bias in a differential receiver on the host the receives the data strobe. A series of read commands are transmitted by the host to the addressed memory chip, which responds by transmitting the normal toggle. Timing of reception of the normal toggle as received by the host chip is adjusted until the normal toggle is correctly received.
