Abstract: One embodiment of the present invention discloses a process of low latency non-volatile memory access using various approaches. In one aspect, a process for low latency memory access to a non-volatile memory (“NVM”) of a solid state drive (“SSD”) is able to generate a submission queue entry (“SQE”) for an SSD memory access by a host to a connected SSD. Upon pushing the SQE from the host to a submission queue (“SQ”) viewable by a controller of the SSD, the counter value of an SQ header pointer is incremented to reflect storage of the first SQE in the SQ. After detecting the SQE in the SQ by a snooping component in the memory controller in accordance with the SQ header pointer, the SQE is fetched from the SQ by the controller and one or more SSD memory instructions are subsequently executed in response to content of the SQE.

Abstract: Methods, systems, and devices are provided for controlling fluid flow in a pressure sensing system. A bi-directional valve can include a first capillary that can couple to a process fluid in a process fluid channel, and a second capillary that can couple to a pressure sensor. The first and second capillaries can include an interface therebetween for controlling fluid flow between the first and second capillaries. The interface region can be configured to allow fluid flow between the first and second capillaries when a magnitude of a pressure difference between the first capillary and the second capillary is less than or equal to a threshold pressure. The interface region can also be configured to prevent fluid flow between the first capillary and the second capillary when the magnitude of the pressure difference between the first capillary and the second capillary exceeds than the threshold pressure.

Abstract: A method and apparatus for certification of facts introduces a certifier and a fact certificate into the fact-exchange cycle that enables parties to exchange trustworthy facts. Certification is provided to a fact presenter during the first part of the fact-exchange cycle, and verification is provided to the fact receiver during the last part of the cycle. To request a certification, a fact presenter presents the Certifier with a fact. In return, the certifier issues a fact certificate, after which the fact presenter presents the fact certificate to the fact receiver instead of presenting the fact itself. The receiver inspects the received certificate in order to evaluate the fact's validity and trustworthiness. For some facts and notions of verification, the certificate is sufficient and its inspection does not require any communication. For others, the receiver requests a verification service from the Certifier in order to complete the verification.

The system also tracks user scorings that accumulate based on the user interaction, and enables certain website features based on these user scorings. The system also tracks ratings for user-uploaded objects and identifies top rated objects for displaying on webpages viewable by other users.

Abstract: A system configuration containing a host, solid state drive (“SSD”), and controller able to perform a hybrid mode non-volatile memory (“NVM”) access is disclosed. Upon receiving a command with a logical block address (“LBA”) for accessing information stored in NVM, a secondary flash translation layer (“FTL”) index table is loaded to a first cache and entries in a third cache is searched to determine validity associated with stored FTL table. When the entries in the third cache are invalid, the FTL index table in the second cache is searched to identify valid FTL table entries. If the second cache contains invalid FTL index table, a new FTL index table is loaded from NVM to the second cache. The process subsequently loads at least a portion of FTL table indexed by the FTL index table in the third cache.

Abstract: One embodiment of the present invention discloses a shared non-volatile memory (“NVM”) system using a distributed flash translation layer (“FTL”) scheme capable of facilitating data storage between multiple hosts and NVM devices. A process of shared NVM system includes an NVM management module or memory controller able to receive a request from a host for reserving a write ownership. The write ownership allows a host to write information to a portion of storage space in an NVM device. Upon identifying availability of the write ownership associated with the NVM device in accordance with a set of predefined policy stored in the NVM management module, the request is granted to the host if the write ownership is available. The host is subsequently allowed to fetch the FTL snapshot from the NVM device for the write operation.
