Abstract: A variety of applications can include a memory device having dynamic page mapping with compression. The memory device can include a mapping table having an entry location to associate a virtual page with a physical address of a first stripe of data of the virtual page. The entry location can include a flag along with the physical address of the first stripe. The flag can identify data of the virtual page as being compressed or uncompressed. A controller of the memory device, responsive to the flag identifying the data of virtual page being compressed, is structured to generate a format of compressed data of the first stripe with a header. The header can include a count of additional physical addresses to store compressed data of the virtual page and the additional physical addresses. Additional apparatus, systems, and methods are disclosed.

Abstract: Methods, systems, techniques, and devices for smart factory reset procedures are described. In accordance with examples as disclosed herein, a memory system may receive one or more commands associated with a reset procedure. The memory system may identify, in response to the one or more commands, a first portion of one or more memory arrays of the memory system as storing user data and a second portion of the one or more memory arrays as storing data associated with an operating system. The memory system may update a mapping of the memory system based on identifying the first portion and the second portion. The memory system may transfer the data associated with the operating system to a third portion of the one or more memory arrays and perform an erase operation on a subset of physical addresses of the set of physical addresses.

Abstract: Apparatuses and techniques for implementing usage-based-disturbance alert signaling are described. The technology allows usage-based-disturbance (UBD) alerts to be externally communicated from a memory device without a dedicated external interface. Rather, UBD alerts are combined with memory error/alert signals and communicated on a shared alert-related interface. UBD tracking occurs at the memory bank level, with corresponding independent UBD alert signals. These signals are efficiently combined to generate an overall UBD alert. A temporary backoff signal is generated when an overall UBD alert is sent. The backoff signal ensures requisite external timing parameters are met while allowing the individual memory banks to generate persistent UBD alerts.

Abstract: Devices and techniques for chained resource locking are described herein. Threads form a last-in-first-out (LIFO) queue on a resource lock to create a chained lock on the resource. A data store representing the lock for the resource holds the previous thread's identifier, enabling a subsequent thread to wake the previous thread using the identifier when the subsequent thread releases the lock. Generally, the thread releasing the lock need not interact with the data store, reducing contention for the data store among many threads.

Abstract: Methods, systems, and devices for techniques for firmware enhancement in memory devices are described. A memory system may include a volatile memory device and a non-volatile memory device, which may store a node address mapping. A host system in communication with the memory system may transmit a command instructing the memory system to transfer at least a portion of the node address mapping from the non-volatile memory device to the volatile memory device. The memory system may transmit a response to the command to the host system indicating a status associated with transferring the portion of the node address mapping.

Abstract: Methods, systems, and devices for techniques for atomic write operations are described. A memory system may determine a set of pages for an atomic write operation in which data associated with a write command is linked together for writing to a non-volatile memory. The memory system may write, to the non-volatile memory, metadata that indicates the set of pages is associated with the atomic write operation. Based on the metadata, the memory system may determine whether each page of the set of pages has been written with data for the atomic write operation. The memory system may then communicate to a host system an indication of a completion status for the atomic write operation based on determining whether each page of the set of pages has been written with the data for the atomic write operation.

Abstract: Methods, systems, and devices for retiring pages of a memory device are described. An ordered set of device information pages may be used to store device information. The device information pages may be in non-volatile memory. Each page may include a counter value of the number of accesses to indicate if the page includes valid data. A flag associated with the page may be set when the counter value reaches a threshold, to retire the page. Upon power-up, the device may determine which page to use, based on the flags. The flag may be stored in the page, or may be separate (e.g., fuse elements). If fuse elements are used, the page may store a programming-in-process flag to indicate when programming of the fuse element may not have been completed before power loss, in which case the programming may be restarted after power is restored.

Abstract: Methods, systems, and devices for on-die formation of single-crystal semiconductor structures are described. In some examples, a layer of semiconductor material may be deposited above one or more decks of memory cells and divided into a set of patches. A respective crystalline arrangement of each patch may be formed based on nearly or partially melting the semiconductor material, such that nucleation sites remain in the semiconductor material, from which respective crystalline arrangements may grow. Channel portions of transistors may be formed at least in part by doping regions of the crystalline arrangements of the semiconductor material. Accordingly, operation of the memory cells may be supported by lower circuitry (e.g., formed at least in part by doped portions of a crystalline semiconductor substrate), and upper circuitry (e.g., formed at least in part by doped portions of a semiconductor deposited over the memory cells and formed with a crystalline arrangement in-situ).

Abstract: A microelectronic device includes a stack structure, a staircase structure, composite pad structures, and conductive contact structures. The stack structure includes vertically alternating conductive structures and insulative structures arranged in tiers. Each of the tiers individually includes one of the conductive structures and one of the insulative structures. The staircase structure has steps including edges of at least some of the tiers of the stack structure. The composite pad structures are on the steps of the staircase structure. Each of the composite pad structures includes a lower pad structure, and an upper pad structure overlying the lower pad structure and having a different material composition than the lower pad structure. The conductive contact structures extend through the composite pad structures and to the conductive structures of the stack structure. Memory devices, electronic systems, and methods of forming microelectronic devices are also described.
