  • Publication number: 20180314781
    Abstract: A true random metastable flip-flop (TRMFF) complier generates an electrical architecture for a TRMFF chain. The complier selects components for the TRMFF chain from a library of standard cells and logically connects these components in accordance with a primitive polynomial to generate the electrical architecture. The TRMFF chain provides a sequence of random numbers from one or more physical processes in accordance with the primitive polynomial. During operation, one or more microscopic phenomena inside and/or outside of the TRMFF chain can cause one or more low-level, statistically random entropy noise signals to be present within the TRMFF chain. The TRMFF chain advantageously utilizes the one or more low-level, statistically random entropy noise signals to provide the sequence of random numbers.

  • Publication number: 20160316002
    Abstract: Primary data for an application is stored at a remotely located first server such as cloud storage. A user of the application may wish to modify or add to the primary data to create supplemental data for which storage is not supported in the first server. Configurations herein include a way to store the supplemental data (e.g., edits, additions, etc.) on a second server at a second storage service provider (e.g. a corporate intranet). Different instances of the application executing on different computer devices by that same user can retrieve the primary data from the first storage service provider as well as retrieve the supplemental data from the second storage service provider.

  • Patent number: 9064550
    Abstract: A memory access operation on a bit cell of a digital memory, e.g., a static random access memory (SRAM), is assisted by reducing the word line control voltage for reading and boosting it for writing, thus improving data integrity. The bit cell has cross coupled inverters for storing and retrieving a logic state via bit line connections through a passing gate transistor controlled by the word line. A level of a word line signal controlling the passing gate transistor is shifted from a first voltage value to a higher second voltage value to begin a memory access cycle. The level of the word line signal is shifted from the second voltage value to a third voltage value less than the second voltage value during the access cycle. The word line signal is maintained at the third voltage value for a time interval during the access cycle.
