摘要： A computer system includes a memory hub for coupling a processor to a plurality of synchronous dynamic random access memory (“SDRAM”) devices. The memory hub includes a processor interface coupled to the processor and a plurality of memory interfaces coupled to respective SDRAM devices. The processor interface is coupled to the memory interfaces by a switch. Each of the memory interfaces includes a memory controller, a cache memory, and a prediction unit. The cache memory stores data recently read from or written to the respective SDRAM device so that it can be subsequently read by processor with relatively little latency. The prediction unit prefetches data from an address from which a read access is likely based on a previously accessed address.

摘要： An ovonic phase-change semiconductor memory device having a reduced area of contact between electrodes of chalcogenide memories, and methods of programming the same are disclosed. Such memory devices include a lower electrode including non-parallel sidewalls. An insulative material overlies the lower electrode such that an upper surface of the lower electrode is exposed. In one embodiment, the insulative material and lower electrode may have a co-planar upper surface. In another embodiment, an upper surface of the lower electrode is within a recess in the insulative material. A chalcogenide material and an upper electrode are formed over the upper surface of the lower electrode. This allows the memory cells to be made smaller and allows the overall power requirements for the memory cell to be minimized.

摘要： A low-current input buffer is disclosed. The buffer uses self-biased N and P channel differential pairs with their outputs tied together. The self-biasing assists in reducing current consumption. The combination of N and P-channel differential pairs results in symmetry across a wide range of reference and supply voltages.

摘要： A system and method to establish the lock point of a digital synchronous circuit (e.g., a DLL) at the center of or close to the center of its delay line is disclosed. The synchronous circuit is configured to selectively use either a reference clock or its inverted version as the clock signal input to the delay line based on a relationship among the phases of the reference clock, the inverted reference clock, and a feedback clock may be used during determination of the phase relationship. The selective use of the opposite phase of the reference clock for the input of the delay line results in centralization of the lock point for most cases as well as improvement in the tuning range and the time to establish the initial lock, without requiring an additional delay line.
