    摘要: A memory module that includes a buffer and a plurality of synchronous memory devices. The memory module also includes bidirectional bus lines, and each of the synchronous memory devices has bidirectional data terminals. The buffer is configured to regenerate signals received on the bus lines for receipt by the synchronous memory devices, and to regenerate signals received from any one of the synchronous memory devices for receipt by the bus lines. The memory module may further include command lines and a clock line for providing commands and a clock signal to the synchronous memory devices via a command buffer. The combined data bus width of the memory module may be greater than the data bus width of any single one of synchronous memory device, and the total address space provided by the memory module may be larger than the data space for any single synchronous memory device.

    摘要: Providing command queuing in embedded memories is provided. In particular, aspects disclosed herein relate to a process through which a status of the queue is communicated to a host from a device. Aspects of the present disclosure use the command structure of the embedded Multi-Media Card (eMMC) standard, such that the host may determine a state of the queue in the device proximate a known end of an in-progress data transfer. In this manner, the host can select a task to commence after completion of a current data transfer while the current data transfer is still ongoing.

    摘要: Systems and methods for fraud monitoring in a payment service are disclosed. An exemplary system includes a first server being located at a first locale and routing a first series of transaction requests. The system includes a second server being located at a second locale and routing a second series of transaction requests. The transactions requests may or may not be associated with a single payment service user account. The system includes a distributed cache storing a set of transaction details of the two series of transaction requests. The system includes a risk service having access to the set of transaction details from the distributed cache. The risk service generates a fraud warning based on a result of a comparison of at least one transaction detail in the set of transaction details and at least one transaction detail of a new transaction request received by the first server.

    摘要: A method of operating a memory controller is disclosed. The method includes transmitting data signals to a memory device over each one of at least two parallel data links. A timing signal is sent to the memory device on a first dedicated link. The timing signal has a fixed phase relationship with the data signals. A data strobe signal is driven to the memory device on a second dedicated link. Phase information is received from the memory device. The phase information being generated internal to the memory device and based on a comparison between the timing signal and a version of the data strobe signal internally distributed within the memory device. A phase of the data strobe signal is adjusted relative to the timing signal based on the received phase information.

    摘要: The present techniques provide systems and methods of controlling access to more than one open page in a memory component, such as a memory bank. Several components may request access to the memory banks. A controller can receive the requests and open or close the pages in the memory bank in response to the requests. In some embodiments, the controller assigns priority to some components requesting access, and assigns a specific page in a memory bank to the priority component. Further, additional available pages in the same memory bank may also be opened by other priority components, or by components with lower priorities. The controller may conserve power, or may increase the efficiency of processing transactions between components and the memory bank by closing pages after time outs, after transactions are complete, or in response to a number of requests received by masters.
