  • Publication number: 20200192824
    Abstract: A security memory device coupled to a host includes: a normal region for storing normal data; a security region for storing security data; and a memory controller, coupled to the normal region and to the security region. In response to a first command which is issued from the host and indicates the security memory device to enter a security field, the memory controller allows the host to access the security region. In the security field, the memory controller performs at least one security command set on the security region. In response to a second command which is issued from the host and indicates the security memory device to exit the security field, the memory controller prohibits the host from accessing the security region.

  • Patent number: 10163522
    Abstract: The present disclosure relates to a substrate having test line letters that are used to identify a test line on an integrated chip, while avoiding contamination of high-k metal gate processes, and a method of formation. In some embodiments, the substrate has a semiconductor substrate. A test line letter structure is arranged over the semiconductor substrate and has one or more trenches vertically extending between an upper surface of the test letter structure and a lower surface of the test line letter structure. The one or more trenches are arranged within the test line letter structure to form an opening in the upper surface of the test line structure that has a shape of an alpha-numeric character.
