Abstract: According to some embodiments, a user vector generator may access information about a user (e.g., a software deployment developer or operator) in a user data store that contains electronic records each associated with different user. Each record may include, for example, a user identifier and user characteristics. Based on the user characteristics, the system may automatically generate a user vector indicating a computing environment skillset level for that user (e.g., beginner, intermediate, or expert). A machine learning privilege assignment platform may receive an indication of the user vector for the user and, based on the user vector and a machine learning algorithm, generate a privilege decision for that user (e.g., when the user attempts to update the system). An indication of the privilege decision may be output, according to some embodiments, to an SMT solver to review the privilege decision before granting the user access to the computing environment.

Abstract: Techniques are provided for programming a self-selecting memory cell that stores a first logic state. To program the memory cell, a pulse having a first polarity may be applied to the cell, which may result in the memory cell having a reduced threshold voltage. During a duration in which the threshold voltage of the memory cell may be reduced (e.g., during a selection time), a second pulse having a second polarity (e.g., a different polarity) may be applied to the memory cell. Applying the second pulse to the memory cell may result in the memory cell storing a second logic state different than the first logic state.

Abstract: A high-density low voltage ferroelectric (or paraelectric) memory bit-cell that includes a planar ferroelectric or paraelectric capacitor. The memory bit-cell comprises 1T1C configuration, where a plate-line is parallel to a word-line, or the plate-line is parallel to a bit-line. The memory bit-cell can be 1TnC, where ‘n’ is a number. In a 1TnC bit-cell, the capacitors are vertically stacked allowing for multiple values to be stored in a single bit-cell. The memory bit-cell can be multi-element FE gain bit-cell. In a multi-element FE gain bit-cell, data sensing is done with signal amplified by a gain transistor in the bit-cell. As such, higher storage density is realized using multi-element FE gain bit-cells. In some examples, the 1T1C, 1TnC, and multi-element FE gain bit-cells are multi-level bit-cells. To realize multi-level bit-cells, the capacitor is placed in a partially switched polarization state by applying different voltage levels or different time pulse widths at the same voltage level.

Abstract: A data access manager is provided on a computing device to manage access to secure files stored in memory. The data access manager intercepts function calls from applications to the memory management unit and determines whether an application is allowed to access secure data stored in the memory of the computing device. When an initial request to map the data is received, the data access manager maps both secure data and clear data, obtaining pointers to both secure and clear data. When an application has permission to access the requested data, the data access manager returns the pointer to the clear data. When an application does not have permission to access the requested data, the data access manager returns the pointer to the secure data.

Abstract: Aspects of the disclosure relate to processing authentication requests to secured information systems using machine-learned user-account behavior profiles. A computing platform may receive an authentication request corresponding to a request for a user of a client computing device to access one or more secured information resources associated with a user account. The computing platform may capture one or more behavioral parameters and activity data associated with one or more interactions with one or more non-authenticated pages. Then, the computing platform may evaluate the one or more behavioral parameters and the activity data using a behavioral profile associated with the user account. Based on this evaluation, the computing platform may identify the authentication request as malicious and may generate and send one or more denial-of-access commands to prevent the client computing device from accessing the one or more secured information resources associated with the user account.
