  • Patent number: 11997212
    Abstract: Methods, systems, and devices for payload validation for a memory system are described. A payload receiver may be a device that includes an array of memory cells configured to store data, and a payload transmitter may be a host of a payload receiver (e.g., a host device) or another device that is in communication with the payload receiver. A payload receiver may be configured to receive an information payload and a signature associated with the information payload. The received signature may be based on the information payload and an identifier of the payload receiver previously provided to the payload transmitter. The payload receiver may generate a signature based on the information payload and the identifier of the payload receiver (e.g., as stored or cached at the payload receiver), and authenticate the information payload based on the received signature and the generated signature.

  • Patent number: 11994984
    Abstract: A computer storage device having a host interface, a controller, non-volatile storage media, and firmware. The firmware instructs the controller to: store a namespace map to map blocks of logical addresses defined in a namespace to first blocks of logical addresses defined in a capacity of the non-volatile storage media; without changing a size of the namespace, adjust the namespace map to map the blocks of the logical addresses defined in the namespace to second blocks of the logical addresses defined in the capacity of the non-volatile storage media (e.g., to consolidate blocks for performance improvement); and translate the logical addresses in the namespace to physical addresses for the non-volatile storage media using the namespace map.

    Abstract: A memory array comprising laterally-spaced memory blocks individually comprises a vertical stack comprising alternating insulative tiers and conductive tiers. Channel-material strings of memory cells extend through the insulative tiers and the conductive tiers. The laterally-spaced memory blocks in a lower one of the conductive tiers comprises elemental-form metal that extends longitudinally-along the laterally-spaced memory blocks proximate laterally-outer sides of the laterally-spaced memory blocks. A metal silicide or a metal-germanium compound is directly against laterally-inner sides of the elemental-form metal in the lower conductive tier and that extends longitudinally-along the laterally-spaced memory blocks in the lower conductive tier. The metal of the metal silicide or of the metal-germanium compound is the same as that of the elemental-form metal. Other embodiments, including method, are disclosed.

  • Patent number: 11996135
    Abstract: Memory devices, systems including memory devices, and methods of operating memory devices are described in which waterfall attacks can be prevented from degrading data by alerting a memory controller that the memory device requests time to perform internal management operations, and should not be sent any further commands (e.g., activate commands) for a predetermined amount of time. In one embodiment, a memory device includes an external pin, a mode register, a memory array including a plurality of rows of memory cells, and circuitry configured to: determine that a criterion to perform an internal management operation on a subset of the plurality of rows has been met, transmit, in response to determining the criterion has been met, a signal to the external pin, determine a duration corresponding to the internal management operation, and write a bit value indicative of the determined duration to the mode register.

  • Patent number: 11996134
    Abstract: Apparatuses, systems, and methods for direct refresh management (DRFM) sampling protection. A memory receives a DRFM address and DRFM sampling command from a controller. The memory also samples addresses into an aggressor register. Responsive to receiving the DRFM address, the memory may prevent addresses which match the DRFM address from being added to the aggressor register for at least a period of time. For example, a protect flag may be activated for the period of time. If the aggressor register already contained an address which matched the DRFM address, it may be removed.

  • Publication number: 20240170091
    Abstract: Described apparatuses and methods provide system error correction code (ECC) circuitry routing that segregates even sense amp (SA) line data sets and odd SA line data sets in a memory, such as a low-power dynamic random-access memory. A memory device may include one or more dies, and a die can have even SA line data sets and odd SA line data sets. The memory device may also include ECC circuitry comprising one or more ECC engines. By segregating the data sets, instead of coupling even and odd SA line data sets to a single ECC engine, double-bit errors on a single word line may be separated into two single-bit errors. Thus, by utilizing system ECC circuitry routing in this way, even a one-bit ECC algorithm may be used to correct double bits, which may increase data reliability.

  • Publication number: 20240170088
    Abstract: Apparatuses, systems, and methods for an enhanced ECC mode. The memory array includes a number of data column planes and an extra column plane. When the memory device is set in an Enhanced ECC mode, data is stored in a subset of the data column planes, and an error correction code circuit (ECC) stores corresponding parity data in one of a column plane other than one of the subset of data column planes or the extra column plane. In this manner, memory may be capable of performing single error correction or single error correction with double error detection (SECDED) depending on the mode selected.

  • Publication number: 20240170038
    Abstract: Described apparatuses and methods relate to adaptive refresh staggering for a memory system that may support a nondeterministic protocol. To help manage power-delivery networks in a memory system, a memory device can include logic that can be programmed to stagger the start of refresh operations for each die upon receiving a command to enter a lower-power mode, such as self-refresh. The staggered start can be implemented at a channel level, a package level, or both. The programming sets a delay for each die so that initiation of refresh operations is staggered. Thus, a first die can initiate refresh operations when a command to enter the lower-power mode is received (e.g., approximately zero delay). However, initiation of refresh operations for subsequent dies (e.g., “after” the first die) is delayed, which can reduce peak current draw and power consumption.

  • Patent number: 11989556
    Abstract: Disclosed in some examples are systems, methods, devices, and machine-readable mediums to detect and terminate programmable atomic transactions that are stuck in an infinite loop. In order to detect and terminate these transactions, the programmable atomic unit may use an instruction counter that increments each time an instruction is executed during execution of a programmable atomic transaction. If the instruction counter meets or exceeds a threshold instruction execution limit without reaching the termination instruction, the programmable atomic transaction may be terminated, all resources used (e.g., memory locks) may be freed, and a response may be sent to a calling processor.

  • Patent number: 11988563
    Abstract: Methods, systems, and devices for temperature exception tracking in a temperature log for a memory system are described. The memory system may store the temperature log separate from data to which the temperature information corresponds. For example, a memory device may store data in a relatively higher-level cell and the corresponding temperature information in a relatively lower-level cell. To perform a write operation, the memory system may determine a current temperature at which the data is being written or was written to a partition of a memory device and may indicate in the temperature log if the current temperature is entering a temperature range that is outside a threshold temperature (e.g., a nominal temperature). To perform a read operation, the memory system may determine if the data to read was written to the memory device outside the threshold temperature to determine whether to perform temperature compensation for the read operation.
