  • 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: 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.

  • 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.

  • 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.

    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.
