<p>PROBLEM TO BE SOLVED: To provide a method for reading a passive matrix-addressable device with individually addressable cells.SOLUTION: The cells store data in the form of one of two polarization states in each cell, and the polarization states in the cells are written and read by addressing via electrodes which form word and bit lines in an orthogonal electrode matrix, and the cells are provided in or at the crossings between the word and bit lines, and a voltage pulse protocol is used according to which electric potentials on all word and bit lines are controlled coordinated in time. During reading, a word line is activated by applying a voltage which is proportional to the potential on all crossing bit lines corresponding to the voltage, and data stored in the cells connected to this active word line are determined by detecting electric charge values of the cells in detection means.</p> |
