  • Patent number: 9921751
    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.

  • Patent number: 9880971
    Abstract: A memory appliance system is described and includes a processor coupled to one or more communication channels with a command interface, wherein the processor is configured for communicating commands over the communication channels. A plurality of Smart Memory Cubes (SMCs) is coupled to the processor through the communication channels. Each of the SMCs includes a controller that is programmable, and a plurality of memory devices. The controller is configured to respond to commands from the command interface to access content stored in one or more of the plurality of memory devices and to perform data operations on content accessed from the plurality of memory devices.

  • Patent number: 9841791
    Abstract: A rack unit configuration is described that includes a first printed circuit board (PCB) assembly interleaved with a second PCB assembly that is inverted with respect to the first PCB assembly. The configuration of the first PCB assembly and the second PCB assembly allow for increased component and power densities within computing systems, memory systems, etc. The increased density may be achieved while allowing sufficient mechanical clearance to allow easy component replacement and servicing (e.g., and hot pluggability). Power density may also be increased with PCB assemblies including nested and interleaved power modules.

  • Patent number: 9824779
    Abstract: In response to a first memory access transaction having a first base address, data fields and a repair fields are retrieved from a first DRAM channel. The data fields include a first data field. The repair fields include a first repair field storing repair data. The repair data is to replace any data in the first data field. In response to a second memory access transaction having a second base address, repair tag fields are retrieved from a second DRAM channel. The repair tag fields include a repair tag field that indicates the repair data is be replace the data stored in the first data field.
