  • Patent number: 11763913
    Abstract: A system can validate multiple nonvolatile random-access memory (NVRAM) devices in parallel. The system can concurrently write a first data to a first volatile memory of a first NVRAM device and a second NVRAM device. The system can modify a first electrical power source that provides an electrical power output that is received by the first NVRAM device and is received by the second NVRAM device to modify a voltage of the electrical power from a first value to a second value to initiate the first NVRAM device and the second NVRAM device to respectively perform a vault. The system can reset the first electrical power source, causing the first NVRAM device and the second NVRAM device to reset. The system can verify whether the first NVRAM device and the second NVRAM device respectively store the first data in volatile memory subsequent to performing the resetting.

  • Patent number: 11755412
    Abstract: Memory devices, systems including memory devices, and methods of operating memory devices are described, in which a host device may directly access a portion of memory array that is otherwise reserved for ECC functionality of a memory device. The memory array may correspond to a set of memory addresses, where each memory address of the set corresponds to a first portion of the memory array (e.g., user data plane) and to a second portion of the memory array (e.g., ECC plane). The second portion may be configured to store ECC data or second user data or metadata based on whether the ECC functionality is enabled or disabled. The memory device may determine a command directed to the memory address of the set is configured to access the first portion or the second portion based on a status of a pin associated with the command.

  • Patent number: 11709731
    Abstract: Methods, systems, and devices for operating memory cell(s) using a direct-input column redundancy scheme are described. A device that has read data from data planes may replace data from one of the planes with redundancy data from a data plane storing redundancy data. The device may then provide the redundancy data to an error correction circuit coupled with the data plane that stored the redundancy data. An output of the error correction circuit may be used to generate syndrome bits, which may be decoded by a syndrome decoder. The syndrome decoder may indicate whether a bit of the data should be corrected by selectively reacting to inputs based on the type of data to be corrected. For example, the syndrome decoder may react to a first set of inputs if the data bit to be corrected is a regular data bit, and react to a second set of inputs if the data bit to be corrected is a redundant data bit.

  • Patent number: 11631473
    Abstract: 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.
