  • Publication number: 20240134982
    Abstract: Examples include techniques for a memory module per row activate counter. The techniques include detecting a row hammer or row disturb condition for a row address at a volatile memory device if an activate count to the row address matches a threshold count. The activate count is maintained by a controller for the memory module. Detection of the row hammer or row disturb condition can cause refresh management actions to mitigate the row hammer or row disturb condition.

  • Publication number: 20240028531
    Abstract: A memory subsystem triggers dynamic switching for memory devices to provide access to active memory devices and prevent access to inactive memory devices. Dynamic switching enables a single bus to switch between multiple memory devices whose capacity otherwise exceeds the capacity of the single bus. A switch can be mounted in a memory module or directly on a motherboard alongside the memory devices. A memory controller can toggle a chip select signal as a single control signal to drive the switch. Each switch includes pairs of field effect transistors (FETs), including any of CMOS, NMOS and PMOS FETs. The switch electrically isolates inactive memory devices to prevent access without the need to electrically short the devices.

  • Patent number: 11237903
    Abstract: Technologies for provisioning error-corrected data for use in in-memory compute operations include a memory that includes a memory media having multiple memory partitions and media access circuitry coupled to the memory media. The media access circuitry is to receive a request to perform an in-memory compute operation on data from the memory media. The request specifies a memory partition of the memory media in which the data is located. The media access circuitry reads the data from the memory partition. The media access circuitry performs error correction on the read data to produce error-corrected read data and stores the error-corrected read data in a temporary buffer for access by one or more in-memory compute operations, in addition to the requested in-memory compute operation.
