    摘要： A circular memory device includes a plurality of bottom electrodes, a plurality of top electrodes, a ferroelectric layer, and a plurality of memory storage locations within the ferroelectric layer at a crossover point of each of the bottom electrodes and each top electrode. Contact pads of the bottom electrodes and top electrodes may include a perimeter that defines an annular sector that allows a memory operation to be performed on the circular memory device across a range of rotational positions. In an example implementation, the memory operation may be performed on the circular memory device regardless of the rotational orientation of the circular memory device relative to a reader.

    摘要： 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. 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.
