DNS Resolution of internal tenant-specific domain addresses in a multi-tenant computing environment
A method and associated systems for a multi-tenant DNS mechanism. A multi-tenant computing environment hosts multiple private overlay networks, each of which comprises one tenant's domain. A multi-tenant DNS agent receives a DNS request to resolve a domain address located within the multi-tenant environment. The agent examines a special record within the request to determine whether the request requires resolving the domain address to an internal tenant-specific network identifier within a tenant's private network. The agent then forwards the request to a DNS server, notifying the server whether the requested address resolution is tenant-specific. If the request is not tenant-specific, the server performs a conventional DNS lookup. But if the request is tenant-specific, the DNS server instead performs a lookup into a tenant-specific local database that allows the domain address to be resolved to an internal address visible only within the multi-tenant computing environment. |

Portal for managing admission of unrecognized devices to an enterprise network
A threat management facility detects a device on an enterprise network and determines whether the device is one of a set of managed devices for the enterprise network. When the device is not one of the set of managed devices, the device may be directed to a portal that manages admission of unrecognized devices onto the enterprise network. Based on a response of the unrecognized device to the portal (e.g., if the unrecognized device does not respond to the portal), the device may be listed on an unclaimed device page published by the portal and accessible to authorized users of the enterprise network. An authorized user may claim the unrecognized device from the unclaimed device page and, in the process, may provide additional information regarding the unrecognized device. Once claimed, the previously unrecognized device may be permitted to communicate over the enterprise network. |

Decoding signals by guessing noise
Devices and methods described herein decode a sequence of coded symbols by guessing noise. In various embodiments, noise sequences are ordered, either during system initialization or on a periodic basis. Then, determining a codeword includes iteratively guessing a new noise sequence, removing its effect from received data symbols (e.g. by subtracting or using some other method of operational inversion), and checking whether the resulting data are a codeword using a codebook membership function. This process is deterministic, has bounded complexity, asymptotically achieves channel capacity as in convolutional codes, but has the decoding speed of a block code. In some embodiments, the decoder tests a bounded number of noise sequences, abandoning the search and declaring an erasure after these sequences are exhausted. Abandonment decoding nevertheless approximates maximum likelihood decoding within a tolerable bound and achieves channel capacity when the abandonment threshold is chosen appropriately. |

Quantization codeword selection for low cost parity checking
Methods, systems, and devices for wireless communications are described. The described techniques provide for generating, by an encoding device, one or more entropy symbols, the length of which changes responsive to errors, stacking the entropy symbols into fixed intervals, and selecting a parity bit. The encoding device may divide entropy symbols that are longer than the fixed interval duration and stack the excess portions of the long entropy symbols with shorter entropy symbols in other intervals. The encoding device may transmit the slacked data packet according to the stacking. A decoding device may receive the data packet, identify the locations of the entropy symbols and the selected parity bit, check the parity of each entropy symbol, identify error bits based on the locations of the entropy symbols within multiple fixed intervals, and may correct error bits based on the stacked intervals, the parity bit, and an error mask. |

Method for making MRAM with small dimension and high qulity
This invention is about a method to make an MRAM element with small dimension, by making an MTJ as close as possible to the via, ideally aligning the MTJ and the via in a direction perpendicular to the wafer surface, for making the MRAM element dimension as small as possible. The invention provides a process scheme to flatten the interface of bottom electrode during film deposition, which ensures a good deposition of atomically smooth MTJ multilayer as close as possible to an associated via which otherwise might be atomically rough. The flattening scheme is first to deposit a thin amorphous conducting layer in the middle of BE deposition and immediately to bombard the amorphous layer by low energy ions to provide kinetic energy for surface atom diffusion to move from high point to low kinks. With such surface flattening scheme, not only the MRAM element can be made extremely small, but its device performance and magnetic stability can also be greatly improved. |

Multi-level self-selecting memory device
Methods, systems, and devices related to a multi-level self-selecting memory device are described. A self-selecting memory cell may store one or more bits of data represented by different threshold voltages of the self-selecting memory cell.

The self-selecting memory cell may include a chalcogenide alloy. A non-uniform distribution of an element in the chalcogenide alloy may determine a particular threshold voltage of the self-selecting memory cell. The shape of the programming pulse may be configured to modify a distribution of the element in the chalcogenide alloy based on a desired logic state of the self-selecting memory cell. |

Enhanced auto-precharge memory scheduling policy
Disclosed embodiments relate to enhanced auto-precharge memory scheduling. In one example, a system includes a memory having a matrix of storage cells, which, responsive to a row address strobe (RAS) signal, activates a given row, responsive to a column address strobe (CAS) signal, selects storage cells in the given row, and, responsive to a combined auto-precharge (AP) and CAS signal, accesses, then closes the given row. A memory controller selects a memory request from a memory request queue, generates the RAS signal to activate a row, when another memory request to the row is enqueued, generates the CAS signal to select a storage cell, when another memory request to a same bank but a different row is enqueued, generates the combined AP and CAS signal, and, when no memory request to the same bank is enqueued, generates the CAS signal only, allowing a close timer to close the row. |

System and method for refreshing data for integrity protection at a thermal excursion event
An information handling system includes a memory array and a memory controller. The memory array stores data within the information handling system. The memory controller writes the data to the memory array. The memory controller also determines whether a temperature of the memory array is above a threshold temperature. The memory controller tags a plurality of memory locations within the memory array written with data while the temperature is above the threshold temperature. While a refresh operation is being executed, the memory controller determines whether the temperature of the memory array is below the threshold temperature. In response to the temperature of the memory array being below the threshold temperature and while the refresh operation is being executed, the memory controller rewrites the data in the tagged memory locations within the memory array. |
