    Abstract: Embodiments of the present disclosure may relate to a data storage controller that may include a non-volatile memory, and a processor coupled with the non-volatile memory to perform a scan of a plurality of non-volatile memory dies in a multi-die memory package to detect one or more defective non-volatile memory dies, where an individual non-volatile memory die of the plurality of non-volatile memory dies is defective if the individual non-volatile memory die has a number of bad blocks that exceeds a predefined threshold, and store one or more defective die indicators in a die topology in the non-volatile memory based at least in part on the scan, where the one or more defective die indicators correspond to the one or more defective non-volatile memory dies. Other embodiments may be described and/or claimed.

    Abstract: According to one configuration, a memory system includes a configuration manager and multiple memory devices. The configuration manager includes status detection logic, retrieval logic, and configuration management logic. The status detection logic receives notification of a failed attempt by a first memory device to be initialized with custom configuration settings stored in the first memory device. In response to the notification, the retrieval logic retrieves a backup copy of configuration settings information from a second memory device in the memory system. The configuration management logic utilizes the backup copy of the configuration settings information retrieved from the second memory device to initialize the first memory device.

    Abstract: Embodiments include apparatuses, method, and systems for organizing individual memory dice of a memory device into a plurality of virtual dice and designating one of the virtual dice of the memory device for storage of redundancy information. In one embodiment, a memory controller includes memory allocation logic to organize memory resources of individual memory dice of a memory device into a plurality of virtual dice, including a redundancy virtual die for storing redundancy information and a plurality of data virtual dice for storing data. The memory controller may further include input/output logic to write data to the data virtual dice of the non-volatile memory device, and redundancy information logic to generate redundancy information based on the data and to write the redundancy information to the redundancy virtual die of the non-volatile memory device.

    Abstract: Techniques for performing background refresh for storage devices using a timestamp from the host are described. In one example, a method involves receiving a timestamp from a host, storing the timestamp in a storage device, and determining a retention time for data stored in one or more blocks of the storage device based on the timestamp relative to a second timestamp indicating when the data was written to the one or more blocks. In response to determining the retention time exceeds a threshold, the storage device moves the data to one or more other blocks of the storage device, which can include interleaving the refresh writes with activity from the host.

    Abstract: Technology for an apparatus is described. The apparatus can include a first non-volatile memory, a second non-volatile memory to have a write access time faster than the first non-volatile memory, and a memory controller. The memory controller can be configured to detect corrupted data in a selected data region in the first non-volatile memory. The selected data region can be associated with an increased risk of data corruption after data is written from the second non-volatile memory to the first non-volatile memory. Uncorrupted data in the second non-volatile memory that corresponds to the corrupted data in the first non-volatile memory can be identified. Data recovery in the first non-volatile memory can be performed by replacing the corrupted data in the first non-volatile memory with uncorrupted data from the second non-volatile memory.

    Abstract: Technologies for managing an operational characteristic of a solid state drive include monitoring the operational characteristic to determine whether the operational characteristic satisfies a low threshold and a high threshold. If the operational characteristic does satisfy the low threshold, the solid state drive throttles high power memory accesses requests while not throttle low power memory access requests. If the operational characteristic satisfies a high threshold, the solid state drive is configured to throttle all memory accesses. The operational characteristic may be embodied as, for example, a temperature of the solid state drive.
