  • Patent number: 11985809
    Abstract: A semiconductor memory cell includes a floating body region configured to be charged to a level indicative of a state of the memory cell selected from at least first and second states. A first region of the memory cell is in electrical contact with the floating body region. A second region of the memory cell is spaced apart from the first region and is also in electrical contact with the floating body region. A gate is positioned between the first and second regions. A back-bias region is configured to generate impact ionization when the memory cell is in one of the first and second states, and the back-bias region is configured so as not to generate impact ionization when the memory cell is in the other of the first and second states.

  • Patent number: 11948709
    Abstract: An all-printed physically unclonable function based on a single-walled carbon nanotube network. The network may be a mixture of semiconducting and metallic nanotubes randomly tangled with each other through the printing process. The unique distribution of carbon nanotubes in a network can be used for authentication, and this feature can be a secret key for a high level hardware security. The carbon nanotube network does not require any advanced purification process, alignment of nanotubes, high-resolution lithography and patterning. Rather, the intrinsic randomness of carbon nanotubes is leveraged to provide the unclonable aspect.
