    摘要: A method for protecting an electronic circuit having at least one output against external radiation includes functionally duplicating the electronic circuit and linking the outputs of the electronic circuit and the duplicated electronic circuit to homologous inputs of at least functionally equivalent combinatorial or sequential elements. The homologous outputs of all the combinatorial or sequential elements are linked together. The electronic circuit can be duplicated multiple times.

    摘要: A memory circuit has a high voltage and low voltage supply nodes. One of a first and second sets of voltages is selectively applied to the supply nodes of the memory circuit in dependence upon memory operational mode. If in active read/write mode, then the first set of voltages is selectively applied. Conversely, if in standby no-read/no-write mode, then the second set of voltages is selectively applied. A low voltage in the second set of voltages is greater than a low voltage in the first set of voltages by a selected one of a plurality of low offset voltages, and a high voltage in the second set of voltages is less than a high voltage in the first set of voltages by a selected one of a plurality of high offset voltages. The offset voltages are provided by diode-based circuits that are selectively active. Selective activation is provided by either selectably blowable fuse elements or selectively activated switching elements.

    摘要: A memory cell is protected against current or voltage spikes. The cell includes a group of redundant data storage nodes for the storage of information in at least one pair of complementary nodes. The cell further includes circuitry for restoring information to its initial state following a current or voltage spike which modifies the information in one of the nodes of the pair using the information stored in the other node. The data storage nodes of each pair in the cell are implanted on opposite sides of an opposite conductivity type well from one another within a region of a substrate defining the boundaries of the memory cell.
