  • Data storage devices with vertical charge transfer
    Patent number: 4559549
    Abstract: A data storage device comprising a planar integrated circuit (13) formed on a face of a body of an electronic storage material which provides a plurality of spaced discrete columns of spaced discrete electric charge storage sites (5), the columns extending in directions normal to the plane of the intergrated circuit and the integrated circuit providing access to the storage sites.

  • Radiation hardness testing for field effect devices
    Patent number: 4220918
    Abstract: A method of testing a field effect device for radiation hardness. The method comprises the steps of subjecting the field effect device to a low temperature environment, developing a first set of data points by measuring the conductance of the field effect device as a function of gate voltage at a first substrate bias, developing a second set of data points by measuring the conductance of the field effect device as a function of gate voltage at a second substrate bias, which is different from the first substrate bias, and comparing the first and second sets of data points to obtain an assessment of radiation hardness.
