    Abstract: Methods, systems, and devices for idle mode temperature control for memory systems are described. A memory system may implement the use of one or more dummy access commands to reduce the effects of errors introduced by temperature changes while the memory system is in an idle mode. For example, performing one or more access commands, such as one or more read commands, may increase a temperature of a memory device and support a desired operating temperature for the memory device while the memory system is in the idle mode. The memory system may measure the temperature of the memory device during the idle mode. If the memory system determines that the temperature of the memory device has fallen below a threshold temperature, the memory system may issue a quantity of dummy access commands to the memory device, and the corresponding dummy access operations may result in a temperature increase at the memory device.

    Abstract: Methods, systems, and devices for using page line filler data are described. In some examples, a memory system may store data within a write buffer of the memory system. The memory system may initiate an operation to transfer the write buffer data to a memory device, for example, due to a command to perform a memory management operation (e.g., cache synchronization, context switching, or the like) from a host system. In some examples, a quantity of write buffer data may fail to satisfy a data size threshold. Thus, the memory system may aggregate the data in the write buffer with valid data from a block of the memory device associated with garbage collection. The memory system may aggregate the write buffer data with the garbage collection data until the aggregated data satisfies the data size threshold. The memory system may then write the aggregated data to the memory device.

    Abstract: Methods, systems, and devices for data separation for garbage collection are described. A control component coupled to the memory array may identify a source block for a garbage collection procedure. In some cases, a first set of pages of the source block may be identified as a first type associated with a first access frequency and a second set of pages of the source block ay be identified as a second type associated with a second access frequency. Once the pages are identified as either the first type or the second type, the first set of pages may be transferred to a first destination block, and the second set of pages may be transferred to a second destination block as part of the garbage collection procedure.

    Abstract: Methods, systems, and devices for read operations for regions of a memory device are described. In some examples, a memory device may include a first cache for storing mappings between logical addresses and physical addresses of the memory device, and a second cache for storing indices associated with entries removed from the first cache. The memory device may include a controller configured to load mappings to the first cache upon receiving read commands. When the first cache is full, and when the memory device receives a read command, the controller may remove an entry from the first cache and may store an index associated with the removed entry to the second cache. The controller may then transmit a mapping associated with the index to a host device for use in a HPB operation.

    Abstract: Methods, systems, and devices for initialization techniques for memory devices are described. A memory system may include a memory array on a first die and a controller on a second die, where the second die is coupled with the first die. The controller may perform an initialization procedure based on operating instructions stored within the memory system. For example, the controller may read a first set of operating instructions from read-only memory on the second die. The controller may obtain a second set of operating instructions stored at a memory block of the memory array on the first die, with the memory block indicated by the first set of operating instructions. The controller may complete or at least further the initialization procedure based on the second set of operating instructions.
