Patents by Inventor Brent M. Ahlquist

Brent M. Ahlquist has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Continuous isochronous read access and measurement of data stored in non-volatile memory
    Patent number: 8572374
    Abstract: A measurement and authentication engine in a nonvolatile memory computes an original hash value on data read from the nonvolatile memory. A measurement and authentication engine in a host processor recomputes the hash value on the data received from nonvolatile memory and checks that the computed hash value matches the hash value generated and transferred from the nonvolatile memory.
    Type: Grant

  • Accelerating integrity checks of code and data stored in non-volatile memory
    Patent number: 7743239
    Abstract: In some embodiments, a command may be used by a host processor to access certain information from a non-volatile memory, together with a message authentication code. That information may be utilized to generate a message authentication code on the processor. Then, in any future accesses, the message authentication code generated by the host processor may be compared to the message authentication code from the non-volatile memory to determine the integrity of data or code that is received from the non-volatile memory.

  • Data invalid signal for non-deterministic latency in a memory system
    Patent number: 7571297
    Abstract: An apparatus, system, and method for a data invalid signal for non-deterministic latency in memory are described. The apparatus may include a memory to determine that data to be buffered for a data burst cannot be guaranteed in time to satisfy a deterministic latency parameter. The memory may provide an indication that the data cannot be guaranteed. Other embodiments are described and claimed.
