Abstract: A non-volatile memory receives a request from a controller to read data stored in the memory. Moving read references are adjusted as a function of the temperature of the memory at which the data was written and the temperature of the memory at which the data is to be read. Moving read references may also be adjusted as a function of the retention time of the data to be read and the word line type of the storage elements in which the data is stored.

Abstract: Technologies for managing a read cache of a solid state drive include establishing a read cache in an otherwise unused region of non-volatile memory of the solid state drive. To do so, a memory region of the non-volatile memory corresponding to the read cache is converted to single-level cell (SLC) mode. For example, the memory region may be converted from a multi-level cell (MLC) or a triple-level cell (TLC) mode to the SLC mode. A drive controller of the solid state drive manages data in the read cache based on a read count associated with the data. For example, data having a relatively high read count may be inserted into the read cache and data having a relatively lower read count may be evicted from the read cache over time. The size of the read cache may be dynamically adjusted over time based on available space and/or operating requirements.

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.
