    摘要: A system and method utilize a memory device that may be accessed by a plurality of controllers or processor cores via respective ports of the memory device. Each controller may be coupled to a respective port of the memory device via a data bus. Each port of the memory device may be associated with a predefined section of memory, thereby giving each controller access to a distinct section of memory without interference from other controllers. A common command/address bus may couple the plurality of controllers to the memory device. Each controller may assert an active signal on a memory access control bus to gain access to the command/address bus to initiate a memory access. In some embodiments, a plurality of memory devices may be arranged in a memory package in a stacked die memory configuration.

    摘要: Methods and apparatus for adjusting a phase difference between clock signals. A first clock signal at a memory controller is adjusted relative to a clock second signal at a memory device. In one embodiment, data is transferred to the memory device according to the first clock signal, which has a predetermined phase relationship with second clock signal. Data received at the memory device is sampled at the memory device according to the second clock signal. Analysis is done of the data on the memory controller and of the received data on the memory circuit. On the basis of the analysis, an adjustment may be made to the phase relationship.
