Abstract: Embodiments include methods, systems, devices, instructions, and media for limiting hot-cold swap wear leveling in memory devices. In one embodiment, wear metric values are stored and monitored using multiple wear leveling criteria. The multiple wear leveling criteria include a hot-cold swap wear leveling criteria, which may make use of a write count offset value. Based on a first wear metric value of a first management group and a second wear metric value of a second management group, the first management group and the second management group are selected for a wear leveling swap operation. The wear leveling swap operation is performed with a whole management group read operation of the first management group to read a set of data, and a whole management group write operation to write the set of data to the second management group.

Abstract: A system controller of a memory system can present multiple physical functions (PFs) to a host computing system. The system controller can store commands from the host in separate queues and uses an arbiter circuit to issue commands. The arbiter can determine a difference value between a quota of commands and a count of commands issued from a respective queue. The quota is derived from a share specified by the host for the respective PF. The arbiter circuit determines a subset of queues by excluding queues that are empty and queues having a negative difference value. The arbiter circuit can randomly choose a selected queue from the subset and issue a command from the selected queue.

Abstract: A determination is made that a source group of data management units of a memory component satisfies a threshold wear condition. A wear leveling operation is performed by copying data from a first data management unit of the source group of data management units to a second data management unit of a destination group of data management units of the memory component. A logical address of the first data management unit is determined. Indicators in a mapping data structure are moved from entries associated with the first data management unit to another entries in the mapping data structure that are subsequent to the entries associated with the first data management unit. The indicators are used to access data requested by a host system at the source group of data management units or at the destination group of data management units.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for expanding search queries. A search system executes a search query based on a search term and the geographic indicator. In response to determining that a number of the search results is less than a threshold number, the search system determines, based on historical search logs from other users in the first geographic region, a likelihood value indicating a likelihood that the other users in the first geographic region expanded the geographic region of their search queries. The search system compares the likelihood value to a threshold likelihood value, and determines, based on the comparison, that the likelihood value meets or exceeds the threshold likelihood value. The search system then executes an expanded search based on the search term and an expanded geographic indicator that encompasses the first geographic region.
