    Abstract: There is provided a memory, comprising: issuing an allocation operation for allocation of a region of a memory by a first process of a plurality of first processes executed in parallel on a first processor, sending a message to a second processor indicating the allocation of the region of the pool of the memory, issuing a free operation for release of the allocated region of the pool of the memory by a second process of a plurality of second processes executed in parallel on a second processor, and releasing, by the first processor, the allocated region of the pool of the memory as indicated in the free operation, wherein a same region of memory is allocated by the first process and released by the second process, wherein the first processes are concurrently attempting to issue the allocation operation and the second processes are concurrently attempting to issue the free operation.

    Abstract: Methods, systems, and devices for memory operations are described. A host system may obtain data for writing to a memory system. 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.

    Abstract: A method for performing data access management of a memory device in a predetermined communications architecture with aid of unbalanced table update and associated apparatus are provided. The method may include: utilizing a memory controller to receive a plurality of host commands from a host device through a transmission interface circuit of the memory controller, receive a set of first data and a set of second data with first and second active blocks according to first and second commands among the host commands, respectively, and update first and second temporary physical-to-logical (P2L) address mapping tables; and in response to a table region of any temporary P2L address mapping table being full, updating a first P2L address mapping table according to the first temporary P2L address mapping table and selectively updating a second P2L address mapping table according to the second temporary P2L address mapping table, for performing subsequent processing.

    Abstract: An example apparatus for sequential garbage collection can include a memory device including a plurality of memory blocks associated with a plurality of logical block addresses (LBAs). The example apparatus can include a controller coupled to the memory device. The controller can be configured to monitor a quantity of read operations and a quantity of write operations associated with a plurality of command sizes performed on a portion of the plurality of memory blocks. The controller can be configured to monitor a quantity of read operations and a quantity of write operations associated with a particular LBA. The controller can be configured to determine a type of garbage collection operation to perform based on the monitoring.

    Abstract: In some examples, a database system accesses a plurality of objects in a remote object store. In response to a query to change data in a first object of the plurality of objects, the database system specifies the first object prior to the change as a first version of the first object, and creates a second version of the first object after the change. The database system maintains metadata identifying unmodified objects of the plurality of objects, and during a garbage collection process when deciding whether to remove a given object of the plurality of objects, accesses the metadata to determine whether the given object has been modified, and prevents removal of the given object in response to determining that the given object is unmodified.
