    • In a method for reducing detrimental phenomena related to disturb voltages in a data storage apparatus employing passive matrix addressing, particularly a memory device or a sensor device, an application of electric potentials conforming to an addressing operation is generally controlled in a time-coordinated manner according to a voltage pulse protocol. In an addressing operation a data storage cell is set to a first polarization state by means of a first active voltage pulse and then, dependent on the voltage pulse protocol, a second voltage pulse which may be a second active voltage pulse of opposite polarity to that of the first voltage pulse, is applied and used for switching the data storage cell to a second polarization state. The addressed cell is thus set to a predetermined polarization state as specified by the addressing operation. The data storage cells of the apparatus are provided in two or more electrically separated segments such that each segment comprises a separate physical address space for the apparatus. In an addressing operation the data are directed to a segment that is selected based on information on prior and/or scheduled applications of active voltage pulses to the segments.

    • In a non-volatile electric memory system a memory unit (4) and a read/write unit (11) are provided as physically separate units. The memory unit (10) is based on a memory material (4) that can be set to at least two distinct physical states by applying an electric field across the memory material. Electrode means and/or contact means are either provided in the memory unit or in the read/write unit and contact means are at least always provided in the read/write unit. Electrodes and contacts are provided in a geometrical arrangement, which defines geometrically one or more memory cells in the memory layer. Contact means in the read/write unit are provided connectable to driving, sensing and control means located in the read/write unit or in an external device connected with the latter. Establishing a physical contact between the memory unit and the read/write unit closes an electrical circuit over the addressed memory cell such that read, write or erase operations can be effected. The memory material of the memory unit can be a ferroelectric or electret material that can be polarized into two discernible polarization states, or it can be a material with a resistive impedance characteristic such that a memory cell of the material can be set to a specific stable resistance value by the application of an electric field.

    • In a method of driving a passive matrix display or memory array of cells comprising an electrically polarizable material exhibiting hysteresis, in particular a ferroelectric material, wherein the polarization state of individual cells can be switched by application of electric potentials or voltages to word and bit lines in the matrix or array, a potential on selected word and bit lines is controlled to approach or coincide with one of n predefined potential levels and the potentials on all word and bit lines are controlled in time according to a protocol such that word lines are sequentially latched to potentials selected among nWORD potentials, while the bit lines are either latched sequentially to potentials selected among nBIT potentials, or during a certain period of a timing sequence given by the protocol connected to circuitry for detecting charges flowing between a bit line or bit lines and cells connecting thereto. This timing sequence is provided with a read cycle during which charges flowing between the selected bit line or bit lines connecting thereto are detected and a “refresh/write cycle” during which the polarization of the cells connecting with selected word and bit lines are brought to correspond with a set of predetermined values.
