Abstract: Methods, systems, and devices for redundant array management techniques are described. A memory system may include a volatile memory device, a non-volatile memory device, and one or more redundant arrays of independent nodes. The memory system may include a first redundant array controller and a second redundant array controller of a redundant array of independent nodes. The memory system may receive a write command associated with writing data to a type of memory cell. Based on the type of memory cell, the memory system may generate parity data corresponding to the data using one or both of the first redundant array controller and the second redundant array controller. In some examples, the first redundant array controller may be configured to generate parity data associated with a first type of failure and the second redundant array controller may be configured to generate parity data associated with a second type of failure.

Abstract: Methods, systems, and devices for identification and storage of boot information at a memory system are described to support transferring boot information to higher reliability memory storage. A memory system may identify boot information stored at a memory array based on a command received from a host system, which may identify the boot information for the memory system, or based on performing a boot procedure with the host system, in which the boot information may be requested from the memory system. After identifying the boot information stored at the memory array, the memory system may move or transfer the boot information from physical addresses associated with lower reliable memory storage to physical addresses associated with higher reliable memory storage.

The storage system may retrieve, via a processor of the storage system, the data associated with the queue. The storage system may compress, via the processor, the data to form compressed data for storage in a memory device of the storage system based on the write command.

Abstract: Methods, systems, and devices for write booster pinning are described. In some examples, a memory device may receive one or more commands (e.g., write commands) while operating in a first mode (e.g., a write booster mode). Some write commands may include an indication to pin the data to one or more SLCs. For example, a first write command may be associated with first data and a first indicator and a second write command may be associated with second data. Both the first data and the second data may be written to one or more SLCs. When maintenance operations are performed on the SLCs, the second data may be moved (e.g., written) to one or more MLCs. Additionally or alternatively, the memory system may receive one or more commands to unpin data (e.g., the first data) such that it may be moved to one or more MLCs during subsequent maintenance operations.

The host system may send, to the memory system, an indication that the data is to be written to the memory system, and the memory system may remove invalid data at the memory system until the memory system has sufficient resources to store the data. Based on the memory system having sufficient resources, the memory system may delay background operations at the memory system until the data has been written to the memory system. The memory system may also create a restore point based on the memory system having sufficient resources and receiving the data. In other examples, the removal of invalid data at the memory system may be delayed until after the data is written to the memory system.
