Patent ID: 11967351
Assignee: NATIONAL TAIWAN UNIVERSITY
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 16:
17. A device, comprising:
a sense amplifier; and
a first bit cell, in a physical unclonable function (PUF) cell array, configured to store a first bit data associated with a first challenge input,
wherein the first bit cell has a first terminal coupled to a first terminal of the sense amplifier, a second terminal coupled to a second terminal, different from the first terminal, of the sense amplifier, and a third terminal coupled to a source line;
wherein when a read operation is performed to the first bit cell in response to a word line coupled to the first bit cell being activated, the sense amplifier is configured to compare a first voltage at the first terminal of the first bit cell with a second voltage at the second terminal of the first bit cell to generate an output signal, that indicates a first data state of the first bit data, as a PUF response output.
