    摘要: To allow a memory controller to synchronize strobe to clock relationship for a DRAM, a register, such as, a flip flop, is incorporated within the DRAM to facilitate the sampling of SCLK with DQS. Likewise, while the DRAM is in a test mode of operation, the memory controller advances or retards the clock to DQS at the memory controller hub (MCH) to achieve the proper DRAM relationship. In one embodiment, the memory controller advances DQS if a binary zero value is read. In contrast, the memory controller retards DQS if a binary one value is read.

    摘要: An embodiment of the present invention is a technique to integrate data for a source synchronous protocol. A delay generator generates at least an integrating strobe from a data strobe synchronizing a data having a data window using the source synchronous protocol. A pulse generator generates a pulse from the at least integrating strobe. An integrating receiver integrates the data over an integration window defined by the pulse. The integration window is within the data window.

    摘要: Embodiments include an on die termination circuit. The on die termination circuit may be programmable. The on die termination circuit may be programmed to compensate for environmental conditions and the physical characteristics of the device. The programmed on die termination circuit allows for faster transfer rates over communication lines by reducing the time needed to recover from signal reflection and similar issues.

    摘要: Disclosed herein is a wake-up circuit for a bias input of a circuit such as a slave DLL circuit, to allow it to be placed in a reduced power mode and be “awoken” (brought up to a control bias level) in a sufficiently small enough amount of time. The wake-up circuit couples a bias input node to a voltage level that is higher then the control bias level in response to a wake-up event, and then it couples the control bias node to the bias input node in response to their voltage levels being sufficiently close to one another.

    摘要: A differential amplifier power supply is derived from the same source that generates the reference voltage for the differential amplifiers. This will ensure the direction of voltage level shifts of these two voltages to be in tandem. That is, these two voltages will move in the same direction due to any variations in the source since they are generated from the same regulator. In this way receiver timing errors can be significantly reduced in source synchronous and common clock interfaces.
