Abstract: Aspects of the present disclosure configure a system component, such as a memory sub-system controller, to dynamically allocate blocks from a free block pool. The controller generates a free block pool that includes a collection of full blocks and a collection of partial good blocks (PGBs) of a set of memory components, a size of a full block in the collection of full blocks corresponding to a combination of two or more PGBs of the collection of PGBs. The controller receives a request to write data. The controller allocates an individual full block from the collection of full blocks or an individual PGB from the collection of PGBs based on determining whether the request to write the data has been received from the host device or the controller of the memory sub-system.

Abstract: Methods, systems, and devices for skipping pages for weak wordlines of a memory device during pre-programming are described. A memory device may be configured to operate in a first mode involving skipping one or more pages (e.g., a lower page (LP)) associated with a set of wordlines. In some examples, a testing system may determine the set of wordlines (e.g., weak wordlines) for which to skip pages according to performance degradation for the wordlines in response to applying a threshold temperature to a test memory device. In the first mode, the memory device may store (e.g., pre-program) data in a subset of pages distinct from the skipped pages. The memory device may switch to a second mode in response to a trigger condition. In the second mode, the memory device may use each page associated with the wordlines and may refrain from skipping the one or more pages.

Abstract: Methods, systems, and devices for a corrective read of a memory device with reduced latency are described. A memory system may identify a read error based on accessing a memory device, and may select a trim setting for a performing a corrective read operation based on a data retention condition associated with the accessed memory device. Such a data retention condition may be associated with a data retention duration, or a cross-temperature condition, among other criteria or combinations thereof. In some implementations, the memory system may select from a subset of possible trim settings, which may be associated with relevant process corners. For example, the memory system may select between a first trim setting that is associated with a relatively large cross-temperature and a relatively short data retention duration and a second trim setting that is associated with a relatively small cross-temperature and a relatively long data retention duration.

Abstract: Aspects of the present disclosure configure a system component, such as a memory sub-system controller, to generate virtual or superblocks using multiple partial good blocks. The controller identifies a first partial good block (PGB) in a set of memory components, the first PGB having first subset of word line groups (WGRs) that are categorized as being non-defective. The controller searches for a second PGB in the set of memory components having a second subset of WGRs that are categorized as being non-defective. The controller computes a total quantity of WGRs based on the first quantity of WGRs in the first subset of WGRs and a second quantity of WGRs in the second subset of WGRs and, in response, combines the first PGB and the second PGB to form an individual virtual block.

Abstract: A variety of applications can include one or more memory devices having user data preloaded for the application prior to reflowing the memory devices on the system platform of the application. A touch-up data refresh method can be implemented to gain read window budget and to improve retention slope to protect the preload content to tolerate reflow to the system platform. Techniques for data preload can include programming preload data into targeted blocks until the targeted blocks are programmed with the preload data and re-programming the preload data over the programmed preload data in the targeted blocks in a same set of memory cells, without an erase between programming and re-programming the preload data. Variations of such techniques can be used to prepare a memory device with preload data followed by performing a reflow of the memory device to a structure for an application to which the memory device is implemented.

Abstract: Methods, systems, and devices for data block refresh during read access are described. In some instances, when an access command (e.g., a read command) is received, a memory system may determine if the associated block is a PSA block. If the block is PSA block, its data may be provided to a host system to satisfy the read command and the block may either be refreshed or may be designated to be refreshed. For example, the block may be refreshed by copying its data to a write cache and writing the data from the cache to a new block. In other instances, an LBA of the block may be stored (e.g., designated) and the LBA may be refreshed when the memory system is idle.

Based on the first temperature satisfying a first threshold, the memory system may write a set of data to a first block of the memory system that is configured with a first rate for performing scan operations to determine error information for the first block.
