Abstract: A host compiles code to perform a set of one or more database operations on target and embeds an indication of whether the target data is randomly accessed data or sequentially accessed data. The compiled code is transmitted to the compute engine inside a memory system that maintains a first portion of memory for storing sequentially accessed data and a second portion of memory for storing randomly accessed data. The memory system (e.g. SSD) maintains reduced size L2P tables in volatile working memory by maintaining coarse L2P tables in the working memory for use with sequentially accessed data and maintaining fine L2P tables in the working memory for use with randomly accessed data. The compute engine uses the compiled code to perform the set of one or more database operations on the target data using the working memory.

Abstract: A memory system (e.g. a solid state drive) includes one or more non-volatile memory die, a controller in communication with the memory die, a local memory connected to (or part of) the controller and a compute engine inside the memory system that is near the location of the data and can be used to perform common data manipulation operations. When the memory system receives instructions to use the compute engine to perform data manipulation operations, the local memory is reallocated such that an amount of space allocated in the local memory for logical to physical translation information is changed based on the one or more data manipulation instructions.

Abstract: A memory system (e.g., a solid state drive, or SSD) uses application-aware ECC schemes to make use of the specifics of a database schema and analytic queries. Only the fields relevant to the query are decoded, other fields are largely ignored. Integrated interleaved (II) codes and product codes approaches are described. Compared to traditional ECC schemes that decode the entire records before any fields to be used by the analytics are available, the new application-aware ECC schemes may achieve orders of magnitudes throughput improvement and/or substantially lower decoder complexity.

Abstract: Techniques are disclosed relating to writing data across multiple storage blocks in a storage device. In one embodiment, physical erase blocks in a bank of a storage device are erasable. Ones of the physical erase blocks may be associated with different respective communication channels. In such an embodiment, a data stripe may be written across a set of physical erase blocks such that the set of physical erase blocks includes physical erase blocks of different banks and includes physical erase blocks associated with different communication channels. In some embodiments, a request to read a portion of the data stripe may be received. In response to the request, a determination may be made that one of the set of physical erase blocks is unavailable to service the request. The request may then be serviced by reassembling data of the unavailable physical erase block.

One embodiment comprises a primary region corresponding to a predefined portion of a primary network persistent memory unit (nPMU) communicatively coupled to at least one client processor node via a communication system, wherein the primary region is assigned to a client process running on the client processor node and is configured to store information received from the client process; and a mirror region corresponding to a predefined portion of a mirror nPMU communicatively coupled to the client processor node via the communication system, wherein the mirror region is assigned to the client process and is configured to store the information received from the client process.

Abstract: A system is described that includes a network interface attached to a persistent memory unit. The persistent memory unit is configured to receive checkpoint data from a primary process, and to provide access to the checkpoint data for use in a backup process, which provides recovery capability in the event of a failure of the primary process. The network interface is configured to provide address translation information between virtual and physical addresses in the persistent memory unit. In other embodiments, the persistent memory unit is capable of storing multiple updates to the checkpoint state. The checkpoint state and the updates to the checkpoint state, if any, can be retrieved by the backup process periodically, or all at once upon failure of the primary process.
