Abstract: An electronic device may include a first non-volatile storage device having a first storage region, a second non-volatile storage device having a second storage region, and a processor. The processor may detect a modification to a data attribute, generate a first unified extensible firmware interface (UEFI) variable including modified data and previous data associated with the data attribute, and store the first UEFI variable in the first storage region via a first UEFI runtime service. Further, the processor may generate a second UEFI variable to include data indicating the modification to the data attribute and a counter to record boot count. Furthermore, the processor may store the second UEFI variable in the second storage region via the first UEFI runtime service. The processor selectively read, via a second UEFI runtime service, the modified data or previous data from the first storage region based on the second UEFI variable.

Abstract: Examples of systems and method described herein provide for accessing memory devices and, concurrently, generating access codes using an authenticated stream cipher at a memory controller. For example, a memory controller may use a memory access request to, concurrently, perform translation logic and/or error correction on data associated with the memory access request; while also utilizing the memory address as an initialization vector for an authenticated stream cipher to generate an access code. The error correction may be performed subsequent to address translation for a write operation (or prior to address translation for a read operation) to improve processing speed of memory access requests at a memory controller; while the memory controller also generates the encrypted access code.

Abstract: At a high level, this invention relates to an AI-based method of and system for storing and accessing content by combining a controlled and managed transactional blockchain method, with a controlled and managed peer to peer segmented file storage method, within a predetermined closed network environment structure. The includes embedding and installing a hardware and software module on an IoT (Internet of Things) device to be deployed, managed and controlled within a closed network environment structure. This controlled method for storing and accessing content is possible because it functions within a closed network of hundreds or thousands of smart devices or so called IoT devices connected via the internet; these devices act as conventional consumer telecommunication electronics products, such as a home or office network router, an IPTV set top box, a smart tablet, a VoIP phone, mobile phone, etc.

Abstract: Systems and methods for performing bosonic quantum error correction (QEC) using Gottesman-Kitaev-Preskill (GKP) states are provided. An ancilla quantum mechanical oscillator is used to probe Gaussian noise experienced by a data quantum mechanical oscillator without disturbing the state of the data quantum mechanical oscillator. The ancilla quantum mechanical oscillator is initialized with a GKP state and entangled with the state of a data quantum mechanical oscillator to correlate any noise experienced by the data state with the state of the ancilla quantum mechanical oscillator. The states are then disentangled, and momentum and position quadrature operators of the ancilla quantum mechanical oscillator are measured and used to perform QEC on the information stored in the data quantum mechanical oscillator.

Abstract: This disclosure describes a programmable device, referred to generally as a data processing unit, having multiple processing units for processing streams of information, such as network packets or storage packets. This disclosure also describes techniques that include enabling data durability coding on a network. In some examples, such techniques may involve storing data in fragments across multiple fault domains in a manner that enables efficient recovery of the data using only a subset of the data. Further, this disclosure describes techniques that include applying a unified approach to implementing a variety of durability coding schemes. In some examples, such techniques may involve implementing each of a plurality of durability coding and/or erasure coding schemes using a common matrix approach, and storing, for each durability and/or erasure coding scheme, an appropriate set of matrix coefficients.

Abstract: A technique is configured to provide various data protection schemes, such as replication and erasure coding, for data blocks of volumes served by storage nodes of a cluster configured to perform deduplication of the data blocks. Additionally, the technique is configured to ensure that each deduplicated data block complies with data redundancy guarantees of the data protection schemes, while improving storage space of the storage nodes. In order to satisfy the data integrity guarantees while improving available storage space, the storage nodes perform periodic garbage collection for data blocks to optimize storage in accordance with currently applicable data protection schemes

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for safety mechanisms to actively detect address faults. An example system includes a first parity generator (112), a second parity generator (128), and a parity checker (116). The first parity generator (112) is to generate a first parity based on a first address information. The first address information corresponds to a desired location to store data in a memory storage array (124). The second parity generator (128) is to generate a second parity based on a second address information. The second address information corresponding to an actual location where the data is stored in the memory storage array (124). The parity checker (116) is to compare the first parity and the second parity to detect a fault.

Abstract: A first serializing stage is provided with a stream of data words composed of sub-words that each have values that associate each of the sub-words with the same error detection code value. For example, the values selected for each sub-word may each be associated with even parity. One or more serializing stages time-multiplex the sub-words into a stream of sub- word sized data. At the serializing stage that receives sub-word sized data stream, the data is checked to determine whether any of the sub-words is no longer associated with the error detection code value. Serializing/deserializing stages are selectively controlled to replace one or more data bits from a word being serialized/deserialized with an error detecting code value (e.g., parity). A subsequent serializing/deserializing stage is enabled to use the inserted error detecting code values and the data in the received words to determine whether an error has occurred.

Abstract: An example computing device includes a connector to establish a wired connection with an electronic device. The computing device also includes a storage device storing a firmware. The firmware is to, in response to detecting a recovery trigger to repair an operating system of the electronic device, identify an operating system of the electronic device. The firmware is also to establish a communication channel between the computing device and the electronic device based on the operating system of the electronic device. The firmware is further to map a virtual network interface of the computing device to a transceiver of the electronic device and retrieve recovery data from a repository via the virtual network interface. The recovery data is transported to the computing device via the communication channel.
