US11216417B2	Systems and methods for scaling beyond maximum number of unique object identifiers in single content repository Disclosed is a new identifier allocation approach for allocating repository object identifiers beyond a maximum number usually allowed for a single repository. The new identifier allocation approach includes an enhanced identifier structure in which a portion usually reserved for a docbase identifier is modified to combine with a partition identifier. The actual docbase identifier is stored in a server configuration file. When the maximum number of object identifiers has been allocated, a new partition is created and a sequence table is updated with a new entry that reflects the new partition. A new repository object identifier is allocated using the docbase identifier combined with the new partition identifier. In this way, more than 4 billion objects per object type can be addressed uniquely within a docbase by creating new partitions. This new approach is very unique and flexible in accommodating both on premises and multi-tenant environments.

US11216385B2	Application processor, system-on chip and method of operating memory management unit Memory management unit (MMU) in an application processor responds to an access request, corresponding to inspection request, including target context and target virtual address and the inspection request is for translating the target virtual address to a first target physical address. The MMU includes context cache, translation cache, invalidation queue and address translation manager (ATM). The context cache stores contexts and context identifiers of the stored contexts, while avoiding duplicating contexts. The translation cache stores first address and first context identifiers second addresses, the first address corresponds to virtual address, the first context identifiers corresponds to first context, and the second addresses corresponds to the first address and the first context. The invalidation queue stores at least one context identifier to be invalidated, of the context identifiers stored in the translation cache. The ATM controls the context cache, the translation cache and the invalidation queue.
US11216379B2	Fast cache loading with zero fill A processor system includes a processor core, a cache, a cache controller, and a cache assist controller. The processor core issues a read/write command for reading data from or writing data to a memory. The processor core also outputs an address range specifying addresses for which the cache assist controller can return zero fill, e.g., an address range for the read/write command. The cache controller transmits a cache request to the cache assist controller based on the read/write command. The cache assist controller receives the address range output by the processor core and compares the address range to the cache request. If a memory address in the cache request falls within the address range, the cache assist controller returns a string of zeroes, rather than fetching and returning data stored at the memory address.
US11216378B2	Techniques for handling cache coherency traffic for contended semaphores The techniques described herein improve cache traffic performance in the context of contended lock instructions. More specifically, each core maintains a lock address contention table that stores addresses corresponding to contended lock instructions. The lock address contention table also includes a state value that indicates progress through a series of states meant to track whether a load by the core in a spin-loop associated with semaphore acquisition has obtained the semaphore in an exclusive state. Upon detecting that a load in a spin-loop has obtained the semaphore in an exclusive state, the core responds to incoming requests for access to the semaphore with negative acknowledgments. This allows the core to maintain the semaphore cache line in an exclusive state, which allows it to acquire the semaphore faster and to avoid transmitting that cache line to other cores unnecessarily.
US11216365B1	Maintenance of non-volaitle memory on selective namespaces This disclosure provides for improvements in managing multi-drive, multi-die or multi-plane NAND flash memory. In one embodiment, the host directly assigns physical addresses and performs logical-to-physical address translation in a manner that reduces or eliminates the need for a memory controller to handle these functions, and initiates functions such as wear leveling in a manner that avoids competition with host data accesses. A memory controller optionally educates the host on array composition, capabilities and addressing restrictions. Host software can therefore interleave write and read requests across dies in a manner unencumbered by memory controller address translation. For multi-plane designs, the host writes related data in a manner consistent with multi-plane device addressing limitations. The host is therefore able to “plan ahead” in a manner supporting host issuance of true multi-plane read commands.

US11216331B2	Memory system and operating method thereof A memory system includes: an ECC unit suitable for generating third data by correcting second data and a third DBI flag by correcting a second DBI flag, based on the second data, the second DBI flag, and a second parity, which are provided through a channel; a DBI unit suitable for generating fourth data by determining whether a plurality of third data bits respectively corresponding to a plurality of DBI flag bits constituting the third DBI flag are inverted, based on the third data and the third DBI flag; and a DM unit suitable for generating a DM flag indicating whether a write operation is performed on a plurality of fourth data bits constituting the fourth data, based on the second data.
