Abstract: In some implementations, a memory device may cache a subset of one or more block family error avoidance (BFEA) lookup tables associated with a block family associated with host data in a first memory location. The block family may be based on at least one of a time window during which the host data was written or a temperature window at which the host data was written. The memory device may receive a read command associated with host data and determine, based on the block family and the subset of the one or more BFEA tables, a threshold voltage offset associated with the host data. The memory device may compute a modified threshold voltage by applying the threshold voltage offset to a base read level voltage associated with the host data. The memory device may read, using the modified threshold voltage, the host data from the first memory location.

Abstract: A plurality of entries associated with a media management operation for a plurality of transfer units are stored. A respective destination location for each of the respective transfer units are determined in connection with the garbage procedure such that a subset of the plurality of transfer units aligns with a codeword boundary on the memory page. A plurality of write commands in connection with the media management operation are issued based at least in part on the determining.

Abstract: Implementations described herein relate to suspending memory erase operations to perform high priority memory commands. In some implementations, a memory device may detect, while an active stage of an erase operation is being performed by the memory device, a pending memory command with a higher priority than the erase operation. The memory device may selectively suspend the active stage of the erase operation, to allow the pending memory command to be executed, based on the active stage of the erase operation that is being performed and/or a value of a suspend determination timer associated with suspending the active stage of the erase operation.

Abstract: A memory device may include logical units configured to store data, wherein the logical units are identified by corresponding logical unit numbers (LUNs) and are associated with corresponding LUN queue groups. Each LUN queue group may include LUN queues that are each associated with a respective intra-LUN priority level that indicates a priority of a LUN queue within a LUN queue group. The LUN queues are each associated with a respective execution priority level that indicates a priority for execution of commands in a LUN queue across LUN queue groups. A quantity of intra-LUN priority levels may be greater than a quantity of execution priority levels. A LUN scheduler may be configured to select and transfer commands from LUN queue groups to the execution queue group based on intra-LUN priority levels. A command executor may be configured to execute commands from the execution queue group based on execution priority levels.
