Abstract

A system for driving a MEMS array having a number of MEMS structures, each defining at least one row terminal and one column terminal, envisages: a number of row driving stages, each for supplying row-biasing signals to the row terminal of each MEMS structure associated to a respective row; a number of column driving stages, each for supplying column-biasing signals to the column terminal of each MEMS structure associated to a respective column; and a control unit, for supplying row-address signals to the row driving stages for generation of the row-biasing signals and for supplying column-address signals to the column driving stages for generation of the column-biasing signals. The control unit further supplies row-deactivation and/or column-deactivation signals to one or more of the row and column driving stages, for causing deactivation of one or more rows and/or columns of the MEMS array.
