  • Patent number: 10453853
    Abstract: A ferroelectric memory cell (1) and a memory device (100) comprising one or more such cells (1). The ferroelectric memory cell comprises a stack (4) of layers arranged on a flexible substrate (3). Said stack comprises an electrically active part (4a) and a protective layer (11) for protecting the electrically active part against scratches and abrasion. Said electrically active part comprises a bottom electrode layer (5) and a top electrode layer (9) and at least one ferroelectric memory material layer (7) between said electrodes. The stack further comprises a buffer layer (13) arranged between the top electrode layer (9) and the protective layer (11). The buffer layer (13) is adapted for at least partially absorbing a lateral dimensional change (?L) occurring in the protective layer (11) and thus preventing said dimensional change (?L) from being transferred to the electrically active part (4a), thereby reducing the risk of short circuit to occur between the electrodes.

  • Patent number: 8184467
    Abstract: In a non-volatile electric memory system a memory unit and a read/write unit are provided as physically separate units. The memory unit is based on a memory material that can be set to at least two distinct physical states by applying an electric field across the memory material. Electrodes and/or contacts are either provided in the memory unit or in the read/write unit and contacts 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. 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 polarized into two discernible polarization states.

  • Patent number: 7646629
    Abstract: In a method for obviating the effect of disturb voltages in a data storage apparatus employing passive matrix addressing, an application of electric potentials for an addressing operation is according to a voltage pulse protocol. The data storage cells of the apparatus are provided in two or more electrically separated segments each constituting non-overlapping physical address subspaces of the data storage apparatus physical address space. A number of data storage cells in each segment are preset to the same polarization by an active voltage pulse with a specific polarization. In a first addressing operation one or more data storage cells are read by applying an active pulse with the same polarization to each data storage cell and recording the output charge response. On basis thereof the output data in subsequent second addressing operation are copied onto preset data storage cells in another segment of the data storage apparatus, this segment being selected on the basis of its previous addressing history.

  • Patent number: 7352612
    Abstract: 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.
