Abstract: Systems and methods are provided for enhancing Universal Flash storage (UFS) power mode transitions by autonomously entering the sleep or power down states upon the expiration of a timer, thereby eliminating the need to reactivate the link between the UFS host and the UFS device to send sleep or power down commands from the UFS host to the UFS device. Eliminating the need to frequently reactivate the link to transition it into sleep and power down states reduces power consumption associated with reactivating the link and keeping it in the active state while the sleep and power commands are transmitted by the UFS host and responded to by the UFS device. In addition, eliminating the need to frequently reactivate the link and keep it active for these purposes reduces latencies associated with issuing the sleep and power down commands.

Abstract: In some aspects, an apparatus includes a processing system that includes one or more processors and one or more memories coupled to the one or more processors. The processing system is configured to send one or more memory access commands to a volatile memory. The one or more memory access commands are associated with a first address. The processing system if further configured to access, based on detecting a row-hammer condition associated with the one or more memory access commands, a physically adjacent row mapping table to determine at least a second address. The first address and the second address correspond to physically adjacent rows within the volatile memory. The processing system if further configured to send one or more row refresh commands to the volatile memory based on the row-hammer condition. The one or more row refresh commands are associated with at least the second address.

Abstract: A host device includes a host controller interface (HCI) configured to be coupled to a flash memory device and configured to receive a notification from the flash memory device that a performance threshold register value has been exceeded while the flash memory device is configured to use a shared write buffer. The HCI is also configured to, in response to receiving the notification, perform a remedial action that includes reassigning a portion of a first logical unit (LU).

Abstract: Data may be purged from a memory device in a manner confined to a particular partition of a memory device having two or more partitions. Logical memory blocks may be de-mapped from physical memory blocks of a first storage partition of the memory device. De-mapped physical memory blocks of the first storage partition may be listed in a local de-mapped block list uniquely associated with the first storage partition. A local purge command may be received from a host device. In response to the local purge command, at least a portion of the de-mapped physical memory blocks listed only in the local de-mapped block list are purged.

Abstract: A host device includes system memory that includes a logical-to-physical (L2P) cache and a second cache. The host device also includes a host controller interface (HCI) configured to be coupled to a flash memory device. The HCI is configured to determine that a particular region of a L2P address mapping table is to be removed from the L2P cache. The L2P address mapping table is configured to include mappings between logical memory addresses and physical memory addresses of the flash memory device. The HCI is also configured to identify a particular sub-region of the particular region having an access metric that satisfies a retention criterion. The HCI is further configured to store the particular sub-region into the second cache. The HCI is also configured to remove the particular region from the L2P cache.

Abstract: Systems and associated methods are described for providing recording of a blacked out media content item. A system receives a request from a first user device associated with a profile to record a media content item scheduled to broadcast on a second user device (different from the first user device) associated with the profile, at a second location. The system determines that the media content item is subject to a blackout during a blackout period within a blackout region. The system determines that the first user device and the second user device are associated with the same profile and that the first user device is at a first location outside the blackout region. The system then accesses the media content item for recording on the second user device during the blackout period. The system further transmits the recorded media content item to the first user device after expiry of the blackout period.

Abstract: Aspects of the present disclosure are directed to techniques and procedures for storing data in a data storage device that uses nonvolatile memory (NVM) to store data. The NVM can be organized into logical units that are assigned respective logical unit numbers. The data storage device can report to a host the amount of spare blocks needed for one or more logical units (LUs), and then the host can relinquish some memory blocks to be reallocated as spare blocks. The data storage device can implement a spare block resource management policy per LU and allocate a predetermined amount of spare blocks per LU. The data storage device can implement a spare block resource management policy per memory type and allocate a predetermined amount of spare blocks for LUs with the same memory type.

Abstract: This disclosure provides systems, methods, and devices for memory systems that support updating a configuration of a physical layer interface (PHY) using information stored in a buffer of a connected memory system. In a first aspect, a method of accessing data in a flash memory system includes initializing, by a memory controller of a host device, a PHY for connecting the host device to a memory system to operate at a first speed, receiving PHY configuration information for configuring the PHY to operate at a second speed, greater than the first speed, from a first buffer of the memory system, and adjusting, by the memory controller, a configuration of the PHY in accordance with the PHY configuration information to operate at the second speed. Other aspects and features are also claimed and described.
