Abstract: Methods, systems, and devices for improved performance in a fragmented memory system are described. The memory system may detect conditions associated with a random access parameter stored at the memory system to assess a level of data fragmentation. The memory system may determine that a random access parameter, such as a data fragmentation parameter, a size of information associated with an access command, a depth of a command queue, a delay duration, or a quantity of commands satisfies a threshold. If one or more of the random access parameters satisfies the threshold, the memory system may transmit a request for the host system to increase an associated clock frequency. The host system may increase the number of commands sent to the memory system in a duration of time. That is, the host system may compensate for a slow-down due to data storage fragmentation by increasing the command processing rate.

Abstract: Methods, systems, and devices supporting techniques for pre-fetching information using pattern detection are described. Some memory systems may support pre-fetching information, such as logical-to-physical (L2P) mapping tables, data, or both, if a sequential pattern of read commands is detected. In some examples, the memory system may store a list of logical addresses indicated by received read commands and may determine whether the list corresponds to a sequential pattern independent of intervening write-alike commands. The list may store previous logical addresses for read commands, allowing the memory system to determine whether subsequent read commands form a sequential pattern. Additionally or alternatively, the memory system may track a ratio of hibernate commands to other commands (e.g., sequential read commands) and may refrain from pre-fetching L2P mapping tables for a detected sequence if the tracked ratio satisfies (e.g., exceeds) a threshold ratio.
