Techniques for memory operations are described. Indications of temperature levels at a memory device may be received, where each of the indications may be associated with a respective time point. Based on an indicated temperature level satisfying a first threshold, a derivative of a temperature of the memory device may be calculated using the indicated temperature levels. Based on calculating the derivative, a determination as to whether the derivative satisfies a second threshold may be determined. If the derivative satisfies the second threshold, operations for accessing the memory device may be modified. A second derivative of the temperature of the memory device may similarly be calculated and compared against a third threshold based on the indicated temperature level satisfying the first threshold. If the second derivative satisfies the third threshold, operations for accessing the memory device may be modified by a different amount.

Modifying access operations based on temperature projections

Methods, systems, and devices for data relocation scheme selection for a memory system are described. A system may select, based on a fragmentation characteristic of data associated with a block of addresses, whether to perform a relocation associated with relocating invalid data, or to perform a relocation associated with refraining from relocating invalid data. A relocation associated with relocating invalid data may be selected for relatively more-fragmented data, which may avoid a relatively higher latency or processing load associated with evaluating validity or updating logical-to-physical mapping at a more-granular level. A relocation associated with refraining from relocating invalid data may be selected for relatively less-fragmented data, which may support increasing available space by relocating data to a physical block with available portions that may be written to, taking advantage of a relatively lower latency or processing load associated with evaluating validity or updating logical-to-physical mapping at a less-granular level.
