    摘要: Techniques and mechanisms for exchanging information between a memory controller and a memory device. In an embodiment, a memory controller receives information indicating for a memory device a threshold number of pending consolidated activation commands to access that memory device. The threshold number indicated by the information is less than a theoretical maximum number of pending consolidated activation commands, the theoretical maximum number defined based on timing parameters of the memory device. In another embodiment, the memory controller limits communication of consolidated activation commands to the memory device based on the information indicating the threshold number.

    摘要: A memory controller to implement targeted refreshes of potential victim rows of a row hammer event. In an embodiment, the memory controller receives an indication that a specific row of a memory device is experiencing repeated accesses which threaten the integrity of data in one or more victim rows physically adjacent to the specific row. The memory controller accesses default offset information in the absence of address map information which specifies an offset between physically adjacent rows of the memory device. In another embodiment, the memory controller determines addresses for potential victim rows based on the default offset information. In response to the received indication of the row hammer event, the memory controller sends for each of the determined plurality of addresses a respective command to the memory device, where the commands are for the memory device to perform targeted refreshes of potential victim rows.

    摘要: A method and system for error management in a memory device. In one embodiment of the invention, the memory device can handle commands and address parity errors and cyclic redundancy check errors. In one embodiment of the invention, the memory can detect whether a received command has any parity errors by determining whether the command bits or the address bits of the received command has any parity errors. If a parity error or cyclic redundancy check error in the received command is detected, an error handling mechanism is triggered to recover from the errant command.

    摘要: Techniques and mechanisms to provide write access to a memory device. In an embodiment, a memory controller sends commands to a memory device which comprises multiple memory banks. The memory controller further sends a signal specifying that the commands include back-to-back write commands each to access the same memory bank. In response to the signal, the memory device buffers first data of a first write command, wherein the first data is buffered at least until the memory device receives second data of a second write command. Error correction information is calculated for a combination of the first data and second data, and the combination is written to the memory bank. In another embodiment, buffering of the first data and combining of the first data with the second data is performed, based on the signal from the memory controller, in lieu of read-modify-write processing of the first data.

    摘要: Techniques and mechanisms for providing state information describing one or more data errors detected locally at a memory device. In an embodiment, the memory device includes a memory core and error detection circuit logic configured to detect for errors of data stored by the memory core. A die of the memory device includes both the memory core and the error detection circuitry. In another embodiment, state information is stored in a mode register of the memory device in response to the error detection logic detecting an occurrence of a data error. The state information is available for access by a memory controller or other agent which is external to the memory device.
