Endurance mechanisms are introduced for memories such as non-volatile memories for broad usage including caches, last-level cache(s), embedded memory, embedded cache, scratchpads, main memory, and storage devices. Here, non-volatile memories (NVMs) include magnetic random-access memory (MRAM), resistive RAM (ReRAM), ferroelectric RAM (FeRAM), phase-change memory (PCM), etc. In some cases, features of endurance mechanisms (e.g., randomizing mechanisms) are applicable to volatile memories such as static random-access memory (SRAM), and dynamic random-access memory (DRAM). The endurance mechanisms include a wear leveling scheme that uses index rotation, outlier compensation to handle weak bits, and random swap injection to mitigate wear out attacks.

Various aspects relate to a memory cell arrangement including: a plurality of spontaneous-polarizable memory cells; and a control circuit configured to cause a writing of one or more first memory cells by a writing operation, wherein the writing operation includes: supplying a write signal set to the plurality of spontaneous-polarizable memory cells to provide a write voltage drop at each of the one or more first memory cells to switch a respective polarization state, the write signal set causing a disturb voltage drop at one or more second memory cells that are not intended to be written, wherein the disturb voltage drop causes a disturb of the one or more second memory cells and maintains a respective polarization state; and wherein the control circuit is further configured to supply a counter-disturb signal set to the plurality of spontaneous-polarizable memory cells, wherein the counter-disturb signal set provides a counter-disturb voltage drop at the one or more second memory cells to at least partially compensate the disturb caused by the write signal set.

An array of non-volatile memory cells includes rows and columns. A volatile storage circuit provides addressable units of storage. A control circuit reads first type data and second type data from one or more of the rows and multiple ones of the columns of the array of non-volatile memory cells. The control circuit stores the first type data and second type data read from each row in one or more addressable units of storage of the volatile storage. A security circuit reads first data from the one or more of the addressable units of the volatile storage and selects from the first data, the second type data that includes one or more bits of each of the one or more of the addressable units. The security circuit performs an integrity check on the selected second type data, and generates an alert signal that indicates a security violation in response to failure of the integrity check.

Some embodiments include an integrated assembly having first electrodes with top surfaces, and with sidewall surfaces extending downwardly from the top surfaces. The first electrodes are solid pillars. Insulative material is along the sidewall surfaces of the first electrodes. Second electrodes extend along the sidewall surfaces of the first electrodes and are spaced from the sidewall surfaces by the insulative material. Conductive-plate-material extends across the first and second electrodes, and couples the second electrodes to one another. Leaker-devices electrically couple the first electrodes to the conductive-plate-material and are configured to discharge at least a portion of excess charge from the first electrodes to the conductive-plate-material. Some embodiments include methods of forming integrated assemblies.

Methods, systems, and devices for imprint recovery management for memory systems are described. In some cases, memory cells may become imprinted, which may refer to conditions where a cell becomes predisposed toward storing one logic state over another, resistant to being written to a different logic state, or both. Imprinted memory cells may be recovered using a recovery or repair process that may be initiated according to various conditions, detections, or inferences. In some examples, a system may be configured to perform imprint recovery operations that are scaled or selected according to a characterized severity of imprint, an operational mode, environmental conditions, and other factors. Imprint management techniques may increase the robustness, accuracy, or efficiency with which a memory system, or components thereof, can operate in the presence of conditions associated with memory cell imprinting.

Methods, systems, and devices for activity-based data protection in a memory device are described. In one example, a memory device may include a set memory sections each having memory cells configured to be selectively coupled with access lines of the respective memory section. A method of operating the memory device may include determining a quantity of access operations performed on a set of sections of a memory device, selecting at least one of the sections for a voltage adjustment operation based on the determined quantity of access operations, and performing the voltage adjustment operation on the selected section. The voltage adjustment operation may include applying an equal voltage to opposite terminals of the memory cells, which may allow built-up charge, such as leakage charge accumulating from access operations of the selected memory section, to dissipate from the memory cells of the selected section.

Further, the memory device may include at least one transistor coupled between the source plate and the ground voltage, wherein a gate of the at least one transistor is coupled to the node. The transistor may be configured to couple the SRC plate to the ground voltage during a processing stage. The transistor may further be configured to isolate the SRC plate from the ground voltage during an operation stage. Methods and electronic systems are also disclosed.
