Abstract
A system includes a memory device configured to store data at addressable locations in the memory device, a physically unclonable function (PUF) device including an array of PUF elements, and a memory interface coupled to the memory device and the PUF device. The memory interface is configured to receive a request to store first data in the memory device, store the first data in the memory device at a first location of the memory device, and transmit the first data and the first location to the PUF device. The PUF device is configured to create a first challenge value using the first data and the first location, generate a first response value using the first challenge value, and store the first response value as a first data integrity tag in the memory device, wherein the first data integrity tag is associated with the first data.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
