    摘要: A memory controller issues a targeted refresh command in response to detection by a distributed detector. A memory device includes detection logic that monitors for a row hammer event, which is a threshold number of accesses to a row within a time threshold that can cause data corruption to a physically adjacent row (a “victim” row). The memory device sends an indication of the row hammer event to the memory controller. In response to the row hammer event indication, the memory controller sends one or more commands to the memory device to cause the memory device to perform a targeted refresh that will refresh the victim row.

    摘要: Methods and apparatus to improve throughput in memory devices are described. In one embodiment, memory throughput is increased via fine granularity of precharge management. In an embodiment, three separate precharge timings may be used, e.g., optimized per memory bank, per memory bank group, and/or per a memory device. Other embodiments are also disclosed and claimed.

    摘要: Techniques and mechanisms to provide selective access to data error information by a memory controller. In an embodiment, a memory device stores a first value representing a baseline number of data errors determined prior to operation of the memory device with the memory controller. Error detection logic of the memory device determines a current count of data errors, and calculates a second value representing a difference between the count of data errors and the baseline number of data errors. The memory device provides the second value to the memory controller, which is unable to identify that the second value is a relative error count. In another embodiment, the memory controller is restricted from retrieving the baseline number of data errors.

    摘要: Exposing internal error correction bits from a memory device for use as metadata bits by an external memory controller. In a first mode the memory device applies internal error correction bits for internal error correction at the memory device. In a second mode the memory device exposes the internal error correction bits to the memory controller to allow the memory controller to use the data.

    摘要: Techniques and mechanisms for determining a count of accesses to a row of a memory device. In an embodiment, the memory device includes a counter comprising circuitry to increment a value of the count in response to detecting a command to activate the row. Circuitry of counter may further set a value of the count to a baseline value in response to detecting a command to refresh the row. In another embodiment, the memory device includes evaluation logic to compare a value of the count to a threshold value. A signal is generated based on the comparison to indicate whether a row hammer event for the row is indicated.
