  • Publication number: 20130058151
    Abstract: Read and write operations of a non-volatile memory (NVM) bitcell have different optimum parameters resulting in a conflict during design of the NVM bitcell. A single bitline in the NVM bitcell prevents optimum read performance. Read performance may be improved by splitting the read path and the write path in a NVM bitcell between two bitlines. A read bitline of the NVM bitcell has a low capacitance for improved read operation speed and decreased power consumption. A write bitline of the NVM bitcell has a low resistance to handle large currents present during write operations. A memory element of the NVM bitcell may be a fuse, anti-fuse, eFUSE, or magnetic tunnel junction. Read performance may be further enhanced with differential sensing read operations.

    Abstract: A storage device contains a smart-card device and a memory device, both connected to a controller. The storage device may be used in the same manner as a conventional smart-card device, or it may be used to store a relatively large amount of data in various partitions. One of these partitions may be a read-only partition that is normally accessible only for read accesses. However, it may sometimes be necessary to update or supplement the data stored in the read-only partition. This is accomplished by a host issuing an appropriate command to the storage device, which may be accompanied by an identifier for an appropriate level of authorization. The controller then changes the attribute of the read-only partition from “read-only” to “read/write” to allow data to be written to the partition. Upon completion, the controller changes the attribute of the partition back to read-only.

    Abstract: To include a superlattice laminate having laminated thereon a first crystal layer of which crystal lattice is a cubic crystal and in which positions of constituent atoms are reversibly replaced by application of energy, and a second crystal layer having a composition different from that of the first crystal layer, and an orientation layer that is an underlaying layer of the superlattice laminate and causes a laminated surface of the first crystal layer to be (111)-orientated. According to the present invention, the laminated surface of the first crystal layer can be (111)-orientated by using the orientation layer as an underlaying layer. In the first crystal layer of which laminated surface is (111)-orientated, a crystal structure reversibly changes when a relatively low energy is applied. Therefore, characteristics of a superlattice device having this crystal layer can be enhanced.

  • Patent number: 8332160
    Abstract: Systems and methods are provided for defining a nucleic acid construct for integration at locus L of an organism. Nucleic acid requests are received, each such request specifying a genetic change to L. The request are expanded into component polynucleotides which are then arranged into {AR1, . . . , ARm} different arrangements, each ARi in {AR1, . . . , ARm} defining a different arrangement of the component polynucleotides. A score Si for each ARi in {AR1, . . . , ARm} is determined based on whether source constructs encoding a portion ofARi are physically present. An ARf in {AR1, . . . , ARm} is selected based on the score for ARf. Primer pairs are calculated to amplify the portions of ARf not represented in the source constructs. The portions of ARf amplified by the primer pairs and the portions of ARf in the source constructs, ordered by ARf, define the nucleic acid construct.
