Abstract: A memory controller integrated circuit includes a clock signal generator circuit configured to generate a plurality of strobe signals. The memory controller integrated circuit further includes a memory interface circuit coupled to the clock signal generator circuit, the memory interface circuit configured to transmit the plurality of strobe signals to a memory module, wherein each of the plurality of strobe signals is offset with respect to an adjacent strobe signal, and transmit a plurality of data signals to the memory module, wherein a first subset of the plurality of data signals comprises a first nibble and is phase aligned with a first strobe signal of the plurality of strobe signals, and wherein a second subset of the plurality of data signals comprises a second nibble and is phase aligned with a second strobe signal of the plurality of strobe signals.

Abstract: A memory system includes a CPU that communicates commands and addresses to a main-memory module. The module includes a buffer circuit that relays commands and data between the CPU and the main memory. The memory module additionally includes an embedded processor that shares access to main memory in support of peripheral functionality, such as graphics processing, for improved overall system performance. The buffer circuit facilitates the communication of instructions and data between CPU and the peripheral processor in a manner that minimizes or eliminates the need to modify CPU, and consequently reduces practical barriers to the adoption of main-memory modules with integrated processing power.
