    Abstract: A channel width can depend on a quantity of memory units (e.g., memory dice) that forms a channel as well as a size of the memory units. A memory system can operate with memory units configured to exchange (e.g., transfer to and/or from) data at a rate of smaller granularity that can provide more various options for channel widths, which can further allow a fine-tuned optimization of the memory system in association with its bandwidth and latency in transferring data from and/or to the memory units. The memory system with such memory units implemented can still provide a degree of data integrity and/or data authenticity required by standardized requirements and/or protocols, such as trusted execution engine security protocol (TSP).

    Abstract: Data protection with error correction/detection capabilities can be provided on a cache line basis. When provided on a cache line basis to collectively protect the cache line data, the error correction/detection capabilities can be provided with fewer number of bits (e.g., error correction code (ECC) and/or cyclic redundancy check (CRC) bits) as compared to providing the same error correction/detection capabilities individually on a subset of the cache line data.

    Abstract: Methods, systems, and devices for data correction schemes with reduced device overhead are described. A memory system may include a set of memory devices storing data and check codes associated with the data. The memory system may additionally include a single parity device storing parity information associated with the data. During a read operation of a set of data, a controller of the memory system may detect an error in data associated with a first check code, the data including two or more subsets of the set of data received from two or more corresponding memory devices. The controller may generate candidate data corresponding to one of the two or more subsets using the parity information and remaining subsets of the set of data. Then the controller may determine whether the candidate data is correct by comparing the first check code with a check value generated using the candidate data.

    Abstract: Methods, systems, and devices for timing parameter adjustment mechanisms are described. The memory system may receive an access command to access a block of data. Based on receiving the access command, the memory system may determine a parameter (e.g., a timing parameter) associated with accessing the block of data. The timing parameter may indicate a duration between a first time to access a first page of the block of data and a second time to access a second page of the block of data. The memory system may perform an access operation on the block of data based on determining the timing parameter.

    Abstract: Systems, apparatuses, and methods related to data stripe protection are described. An error management component can process multiple read/write/recovery requests concurrently. When read/write requests are to be processed on respective strips of a stripe, the error management component can process (e.g., concurrently) the read/write requests to determine a quantity of errors within each one of the strips and the determined quantity can be used to further determine whether to access other memory portions to correct the determined quantity.

    Abstract: The present disclosure includes apparatuses, methods, and systems for programming codewords for error correction operations to memory. An embodiment includes a memory having a plurality of groups of memory cells, wherein each respective one of the plurality of groups includes a plurality of sub-groups of memory cells, and circuitry configured to program a portion of a codeword for an error correction operation to one of the plurality of groups of memory cells by determining an address in that group of memory cells by performing an XOR operation on an address of one of the plurality of sub-groups of that group of memory cells, and programming the portion of the codeword to the determined address.

    Abstract: Systems, apparatuses, and methods related to a controller for managing multiple types of memory are described. A controller includes a front end portion, a central controller portion, a back end portion, and a management unit can manage a first type of memory device that operates according to a first set of timing characteristics and a second type of memory device that operates according to a second set of timing characteristics. The central controller portion is configured to cause performance of a memory operation and comprises a cache memory to buffer data associated performance of the memory operation, a security component configured to encrypt the data before storing the data in the first type of memory device or the second type of memory device, and error correction code (ECC) circuitry to ECC encode and ECC decode the data.

    Abstract: Methods, systems, and devices for operational modes for reduced power consumption in a memory system are described. A memory device may be coupled with a capacitor of a power management integrated circuit (PMIC). The memory device may operate in a first mode where a supply voltage is provided to the memory device from the PMIC. The memory device may operate in a second mode where it is isolated from the PMIC. When isolated, a node of the memory device (e.g., an internal node) may be discharged while the capacitor of the PMIC remains charged. When the memory device resumes operating in the first mode, a supply voltage may be provided to it based on the residual charge of the capacitor.
