A memory system includes dynamic random-access memory (DRAM) components that include interconnected and redundant component data interfaces. The redundant interfaces facilitate memory interconnect topologies that accommodate considerably more DRAM components per memory channel than do traditional memory systems, and thus offer considerably more memory capacity per channel, without concomitant reductions in signaling speeds. The memory components can be configured to route data around defective data connections to maintain full capacity and continue to support memory transactions.

A data backup method of a storage device which includes a storage controller, a buffer memory, and a plurality of nonvolatile memory devices, the method including: detecting a power-off event of an external power provided to the storage device; deactivating a host interface of the storage controller in response to the detection of the power-off event: moving data stored in the buffer memory to a static random access memory (SRAM) in the storage controller; blocking or deactivating a power of the buffer memory; setting an interleaving mode of the plurality of nonvolatile memory devices to a minimum power mode; and programming the data moved to the SRAM to at least one of the plurality of nonvolatile memory devices.

A method and memory device of controlling a plurality of low power states are provided. The method includes: entering a low power mode state, in which memory cell rows of the memory device are refreshed and power consumption is lower than in a self-refresh mode state, in response to a low power state entry command; and exiting the low power mode state based on a low power mode exit latency time that is set in a mode register of the memory device or at least one of an alarm signal and a low power mode exit command.

Embodiments of this application disclose a data processing method, which is used in a storage system. The method in embodiments of this application includes: A network interface card device receives a first access request of a first client, where the first access request carries an access address; the network interface card device detects whether the first access request has a conflict; and when the network interface card device detects that the first access request has a conflict, the network interface card device processes the conflict according to a processing policy. In embodiments of this application, when a conflict occurs, the network interface card device processes the conflict according to the processing policy. This avoids conflict management performed by a processor of a storage node, and saves a resource of the processor of the storage node.

Examples of the present disclosure generally relate to integrated circuits, such as a system-on-chip (SoC), that include a memory subsystem. In some examples, an integrated circuit includes a first master circuit in a first power domain on a chip; a second master circuit in a second power domain on the chip; and a first memory controller in a third power domain on the chip. The first master circuit and the second master circuit each are configured to access memory via the first memory controller. The first power domain and the second power domain each are separate and independent from the third power domain.

Embodiments described herein include a sensor control device configured for secure over-the-air (OTA) programming. Embodiments include a sensor control device that includes one or more processors, an analyte sensor, a communication module, and a memory. The memory includes a first set of storage blocks that are in a non-programmable state and a second set of blocks that are in a programmable state. The processors are configured to receive, using the communication module, instructions to write marking data to the memory to mark a first storage block from the first set of storage blocks as inaccessible and to write program data to a second storage block from the second set of storage blocks, causing the second storage block to be placed into the non-programmable state. The program data written to the second storage block includes instructions that cause the processors to process analyte data received from the analyte sensor.

Methods, systems, and devices for dynamically tuning host performance booster thresholds are described. A memory system may include a set of memory devices and an interface configured to communicate commands with a host system coupled with the memory system. The interface may communicate commands to the memory system according to a first command mode associated with a logical address space including a plurality of regions and communicate commands according to a second command mode associated with physical memory address. The memory system may further include a controller that may determine a region activated for the second command mode, receive a first plurality of commands, determine, upon deactivating the region, a first threshold based on a first quantity of read commands serviced according to the second command mode. The controller may activate the region for the second command based on a second quantity of read commands received exceeding the first threshold.

Storage devices are configured to be utilized in a variety of blockchain related activities that rely on a proof of space consensus model. These storage devices are required to process a lot of read and write cycles on their memory devices to generate the desired proof of space consensus data. The generation and storing of this generated data requires very different types of memory device usage. Storage devices may be configured with a first partition for high-speed access for generating the data, while a second partition is also configured for long-term storage of the generated data. As memory devices reach their estimated end-of-life, they can be dynamically reassigned to the second partition. Likewise, some storage devices may be equipped with multiple memory arrays of different types of memory devices. One set of memory devices can be used for generation, while cheaper, write-once or few memory devices are provided for storage.

The non-volatile memory storage includes independent locations that may be planes or dies. The first superblock includes first blocks corresponding to first independent locations, and the second superblock includes second blocks corresponding to second independent locations. A first number of the first independent locations is less than a number of the independent locations. A second number of the second plurality of independent locations is less than the number of the independent locations.

An information handling system may include at least one processor; a network interface; and a physical storage resource including a flash translation layer (FTL) operable to provide a mapping between logical storage addresses and physical storage addresses. The information handling system may be configured to: receive a request for a snapshot; for used portions of the physical storage resource, change a metadata identifier from a used status to a snapshot status; prevent deletion of those portions associated with the snapshot status; and transmit, via the network interface, information associated with the portions that are associated with the snapshot status.
