PURPOSE:To intend to decrease the number of total selectors by forming matrices by multistage, and by decreasing the number of selectors which are provided at the part of multistage matrices. CONSTITUTION:Matrices consists of small matrix groups L10, L20- in the X axis direction and small matrix groups M1-Mn in the Y axis direction. For the small matrix M1, selectors SW are provided at all intersection points of drop circuits m1y1-m2ym and selection lines m1x1-m1xm. On the other hand, for the small matrices L10, L20-, the selectors SW are provided at only diagonal intersection points of selection lines m1x1-m1xm and local lines l1x1, l1x2- of the small matrix M1. Thus, matrices are formed by multistage and the number of selectors of the other is decreased. Therefore, the number of total selectors can be decreased. |
