    Abstract: Memory system enabling memory mirroring in single write operations. The memory system includes a memory channel which can store duplicate copies of a data element into multiple locations in the memory channel. The multiple locations are disposed in different memory modules and have different propagation times with respect to a data signal transmitted from the memory controller. In a write operation, the relative timings of the chip select, command and address signals among the multiple locations are adjusted according to the data propagation delay. As a result, a data element can be written into the multiple locations responsive to a data signal transmitted from the memory controller in a single transmission event.

    Abstract: An integrated circuit device is disclosed. The integrated circuit device includes a semiconductor die fabricated by a front-end semiconductor process and having oppositely disposed planar surfaces. The semiconductor die is formed with semiconductor devices, power supply circuitry coupled to the semiconductor devices, decoupling capacitance circuitry, and through-vias. The through-vias include a first group of vias coupled to the power supply circuitry and a second group of vias coupled to the decoupling capacitance circuitry. Conductors are formed in a first metal layer disposed on the semiconductor die in accordance with a back-end semiconductor process. The conductors are configured to couple to the first and second groups of through-vias to establish conductive paths from the power supply circuitry to the decoupling capacitance circuitry.

    Abstract: A method and system for direct memory transfers between memory modules are described that includes sending a request to a first memory module and storing the data sent on a memory bus by the first memory module into a second memory module. The direct transfer of data between the first and second memory modules reduces power consumption and increases performance.
