摘要:
In a method for parallel writing and reading of data in an optical memory, the optical memory includes one or more microlenses for accessing a memory medium, individually addressable elements arranged in one or two-dimensional matrices in a write/read device are activated. The activation of an element physically influences one or more localized areas in a data carrying layer in the memory for writing and reading of data carrying structures in the localized area. Writing and reading is thus performed on the basis of a relationship between the geometric location of the element in the matrix and the position of the localized area(s) in the data carrying layer of the memory. A write/read device includes individually addressable elements which are arranged in one or two-dimensional matrices, the addressable element being arranged to be activated in order to physically influence one or more of the above-mentioned localized areas. Use for such a configuration includes, for example, writing and reading in optical memories which consist of 1-100 microlenses with associated data carrying layers and in optical memories which consist of a transparent spherical particle having a transparent layer to which is applied a data carrying film arranged on one side thereof.

Electrically conducting and/or semiconducting structures are generated in three dimensions in a composite matrix including two or more materials provided in spatially separate and homogenous material structures. Materials undergo specific physical and/or chemical changes causing transition from electrically non-conducing to electrically conducting and semiconducting state. The material structures are radiated with a given intensity or frequency characteristic adapted to the specific response of the material. Spatially modulating the radiation according to a protocol representing a pattern of electrically conducing and semiconducting structures in the relevant material structures generates the two dimensional electrically conducting and semiconducting structures in the material structure. The composite matrix is provided with electrically conducting and semiconducting structures in three dimensions. Spectral ranges of the radiation include gamma, x-ray, ultraviolet, visible light, inferred, and microwave. Particle radiation used for irradiation includes elementary particles including protons, neutrons, electrons, ions, molecules, and material aggregates.

In a method for determining the logic state of memory cells in a passive matrix-addressable data storage device with word and bit lines, components of current response are detected and correlated with a probing voltage, and a time-dependent potential is applied on selected word and bit lines or groups thereof, said potentials being mutually coordinated in magnitude and time such that the resulting voltages across all or some of the non-addressed cells at the crossing points between inactive word lines and active bit lines are brought to contain only negligible voltage components that are temporally correlated with the probing voltage. A first apparatus according to the invention for performing the method provides sequential readout of all memory cells on an active word line (AWL) by means of detection circuits (3; 4). An active word line (AWL) is selected by a multiplexer (7), while inactive word lines (IWL) are clamped to ground during readout. A second apparatus for performing the method is rather similar, but has only a single detection circuit (3, 4). An active word line (AWL) is selected by multiplexer (7) and a bit line (ABL) is selected by a multiplexer (9) provided between one end of the bit lines (BL) and the input of the detection circuit (3, 4), while inactive word and bit lines (IWL; IBL) are clamped to ground during readout.
