  • Patent number: 11552087
    Abstract: Various embodiments of the present application are directed towards an integrated memory chip comprising a memory array with a strap-cell architecture that reduces the number of distinct strap-cell types and that reduces strap-line density. In some embodiments, the memory array is limited to three distinct types of strap cells: a source line/erase gate (SLEG) strap cell; a control gate/word line (CGWL) strap cell; and a word-line strap cell. The small number of distinct strap-cell types simplifies design of the memory array and further simplifies design of a corresponding interconnect structure. Further, in some embodiments, the three distinct strap-cell types electrically couple word lines, erase gates, and control gates to corresponding strap lines in different metallization layers of an interconnect structure. By spreading the strap lines amongst different metallization layers, strap-line density is reduced.

  • Patent number: 11445071
    Abstract: A document processing device, a document processing system, and a data processing method for the same are introduced. The document processing device utilizes an exclusive user identification information and an exclusive phone number information. After obtaining a document image, all the document image, the exclusive user identification information and the exclusive phone number information are used to generate document image file information. The document image file information is transmitted to a remote storage through a mobile network. Since the document image file information is directly sent by the document processing device to the remote storage according to the unique user identification and unique phone number information through the mobile network, not only can the cumbersome and complicated configuration process be avoided, but also the risk of information theft can be reduced, thereby improving information storage specificity, confidentiality, and security.
