    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 memory subsystem includes a group of memory devices connected to an address bus. The memory subsystem includes logic to uniquely map a physical address of a memory access command to each memory device of the group. Thus, each physical address sent by an associated memory controller uniquely accesses a different row of each memory device, instead of being mapped to the same or corresponding row of each memory device.

    摘要: Embodiments of an apparatus, system and method for using Per DRAM Addressability (PDA) to program Multi-Purpose Registers (MPRs) of a dynamic random access memory (DRAM) device are described herein. Embodiments of the invention allow unique 32 bit patterns to be stored for each DRAM device on a rank, thereby enabling data bus training to be done in parallel. Furthermore, embodiments of the invention provide 32 bits of storage per DRAM device on a rank for the system BIOS for storing codes such as MR values, or for any other purpose (e.g., temporary scratch storage to be used by BIOS processes).

    摘要: In some embodiments, a chip includes a scheduler, transmitters, receivers, and control circuitry. The schedule schedules signals to be transmitted outside the chip and the transmitters transmit the scheduled signals outside the chip. The receivers receive signals including signals with temperature information related to a temperature outside the chip. The control circuitry selectively limit a number of commands that can be scheduled within a series of smaller windows while checking the temperature information near the conclusion of a larger window comprising many smaller windows. Other embodiments are described.
