    • In a ferroelectric data processing device for processing and/or storage of data with passive or electrical addressing a data-carrying medium is used in the form of a thin film (1) of ferroelectric material which by an applied electric field is polarized to determined polarization states or switched between these and is provided as a continuous layer in or adjacent to electrode structures in the form of a matrix. A logic element (4) is formed at the intersection between an x electrode (2) and a y electrode (3) of the electrode matrix. The logic element (4) is addressed by applying to the electrodes (2, 3) a voltage greater than the coercivity field of the ferroelectric material. Dependent on the polarization state and the form of the hysteresis loop of the ferroelectric material a distinct detection of the polarization state in the logic element (4) is obtained and it may also be possible to switch between the polarization states of the logic element, which hence may be used for implementing a bistable switch or a memory cell. The data processing device according to the invention may be stacked layerwise if the separate layers are separated by an electrical isolating layer and hence be used for implementing volumetric data processing devices.
    • 在用于处理和/或存储具有无源或电寻址数据的铁电数据处理设备中,以铁电材料的薄膜(1)的形式使用数据载体介质,所述铁电材料的薄膜(1)通过施加的电场被极化以确定极化 状态或者在它们之间切换,并且以矩阵形式的电极结构中或附近的连续层提供。 逻辑元件(4)形成在电极矩阵的x电极(2)和y电极(3)之间的交叉处。 逻辑元件(4)通过向电极(2,3)施加大于铁电材料的矫顽力场的电压来寻址。 取决于铁电材料的偏振态和磁滞回线的形式,可以获得逻辑元件(4)中偏振态的明显检测,并且还可以在逻辑元件的偏振态之间切换,其中 因此可以用于实现双稳态开关或存储单元。 如果分离的层被电隔离层隔开并且因此用于实现容积式数据处理设备,则根据本发明的数据处理设备可以层叠地层叠。

    • An electrically addressable passive device for registration, storage and/or processing of data comprises a functional medium (1) in the form of a continuous or patterned structure (S) which may undergo a physical or chemical change of state. The functional medium (1) comprises individually addressable cells (2) which represent a registered or detected value or are assigned a predetermined logical value for the cell. The cell (2) is provided between the anode (3) and cathode (4) in an electrode means (E) which contacts the function medium in the cell and causes an electrical coupling therethrough, the functional medium having a non-linear impedance characteristic, whereby the cell (2) directly can be supplied with energy which effects a change in the state of the cell. In a method for electrical addressing of the passive device wherein the addressing comprises operations for i.a. detection and registration as well as further operations for writing, reading and switching of a logical value assigned to the cell, electric energy is applied directly to the functional medium of the cell in order to change its state and hence effect an addressing operation. Use in optical detector means, volumetric data storage devices or data processing devices.
