摘要:
Various embodiments are directed to apparatuses and methods for faster solid state drive (SSD) boot-up. On boot-up, SSD control algorithms may load non-logical to physical (L2P) parts of a context and signal the system that the SSD is ready. The context may comprise various state data pertaining to the SSD. After signaling that the SSD may be ready to receive access requests, the SSD control algorithms may begin loading segments of the L2P table sequentially. Access to the L2P table may be blocked, however, when a requested segment has not yet been loaded. In such cases, the SSD control algorithms may then load the requested segment out of turn and then service the access request.
摘要:
Techniques to utilize a very low power state with a memory subsystem that includes one or more non-volatile memory devices and a volatile memory system. A memory controller is coupled with the one or more non-volatile memory devices and the volatile memory system. The memory controller comprising at least an embedded control agent and memory locations to store state information. The memory controller to selectively enable and disable the one or more non-volatile memory devices. The memory controller transfers the state information to the volatile memory system prior to entering a low power state. Control circuitry is coupled with the memory controller. The control circuitry to selectively enable and disable operation of the memory controller.
摘要:
An apparatus, as well as systems, methods, and articles can operate to record the address of write operations to a memory cached by a non-volatile cache prior to executing an operating system cache driver. In an embodiment, a non-volatile cache may be implemented by creating a device option read only memory (ROM), or modifying the associated computer basic input-output system (BIOS) to trap software interrupts associated with disk and other media access requests. Associated addresses, such as logical block addresses, can be stored in a log for data that is modified. The resulting log can be stored in a non-volatile medium, including the cache itself. If the available log space is not large enough to record all write activity prior to loading operating system drivers, a flag may be set to indicate the overrun condition.

Methods and apparatus related to management and/or support of metadata for PCMS (Phase Change Memory with Switch) devices are described. In one embodiment, a PCMS controller allows access to a PCMS device based on metadata. The metadata may be used to provide efficiency, endurance, error correction, etc. as discussed in the disclosure. Other embodiments are also disclosed and claimed.
摘要:
A method is described that involves sending a second command over a Serial ATA interface to a device before the device is able to execute a first command that was previously sent to the Serial ATA interface. In a further embodiment of the first command is tagged with a first reference number. In an even further embodiment of the method the second command is tagged with a second reference number.
摘要:
A system and method for generating a transportable physical level data block trace for a computer system. The method comprises capturing a first physical level data block trace on a first computer system, then performing a reverse file system lookup to generate a logical representation of that trace. That logical representation may be delivered to a second computer system, which may perform a file system lookup to convert the logical representation to a second physical level data block trace for a sequence of disk block accesses resulting from executing an application on the second computer system.

Apparatus, systems, and methods to manage memory latency operations are described. In one embodiment, an electronic device comprises a processor and a memory control logic to receive data from a remote memory device, store the data in a local cache memory, receive an error correction code indicator associated with the data, and implement a data management policy in response to the error correction code indicator. Other embodiments are also disclosed and claimed.
