Abstract:
1. A semiconductor device comprising: a plurality of data lines running in one direction on a substrate; a plurality of control lines running in a direction perpendicular to the data lines; a plurality of current load cells each of which is set at the intersection of the respective data lines and control lines, and includes a current load and a current load driving circuit for driving the current load; and a selector having an input terminal to which one current output from a driver for current-driving the data lines is input, and a plurality of output terminals connected to the plural data lines, respectively; wherein: the selector selects one of the plural data lines according to an output select signal input therein, and supplies the current output from the driver to the selected data line; the plural data lines connected to the selector are connected to their corresponding current load cells, respectively; the current load driving circuit in each of the current load cells includes: there are control lines each transmitting a control signal corresponding to the first switch or the first and second switches of the current load driving circuit in each of the current load cells connected respectively to the data lines connected to the selector at least as many as data lines connected to the selector; and in each of the plural current load cells, the control signal corresponding to each of the current load cells is supplied to the control terminal of the first switch, or the control terminals of both the first and second switches of the current load driving circuit.
