    • A sense amplifier system for sensing the charge of a charge-­storing means (601) comprises a first and second charge reference means (600a, 600b) connected in parallel and similar to the charge-storing means (601) and having respectively opposite polarization. The charge reference means (600a, 600b) and the charge-storing means (601) have a common input node (WL), and first and second pseudo-differential reference sense amplifiers (RSA1, RSA2) are connected with output nodes (RBL1, RBL2) of the charge reference means (600a, 600b) for generating reference signals to a common reference node (CHREF) connected with a pseudo-differential sense amplifier (SA). The pseudo-differential sense amplifier (SA) has a second input for receiving an output signal from the charge-storing means (601) and generates an output signal indicative of a polarization state of the charge-storing means. Another embodiment adapted for sensing the charges of a plurality of charge-storing means (701) and comprising at least two pairs of charge reference means is also described. A non-volatile matrix-addressable memory system comprising an electrical polarizable dielectric memory material exhibiting hysterisis and a sense amplifier system as described is also claimed.

    • In a multistable optical logic element with a light-sensitive organic material (1) which undergoes a photocycle with several physical states by irradiation with light, and wherein a physical state is assigned a logical value which can be changed by addressing the element optically, the element initially before the addressing is in a metastable state generated in advance. A multistable optical logic element has been made proximity-addressable by providing at least a color light source (2) for optical addressing and at least one color-sensitive optical detector (5) adjacent to the light-sensitive material. In a method for preparing of the light-sensitive material (1) a desired initial metastable state is generated in the photocycle and assigned a determined logical value for the element. In a method for optical addressing of the optical logic element steps for respectively writing and storing, reading, erasing and switching comprises generating transitions between states in the photocycle and detection of the states. Use in an optical logical device for storing and processing of data.

    • 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.
