Abstract

A matrix array is provided in which the cores are positioned in a triangular configuration. Two drivers in the same group can select a particular core. For example, in order to select core 10, the drivers connected to lines 13 and 15 are energized.

Triangular Matrix Array

A matrix array is provided in which the cores are positioned in a triangular configuration. Two drivers in the same group can select a particular core. For example, in order to select core 10, the drivers connected to lines 13 and 15 are energized.

This is in contrast to conventional rectangular matrices in which a driver in an X group and a driver in a Y group are energized to select a core at the intersection of their associated lines. Mathematically, it has been established that the relation of the number of lines to the number of cores in the triangular matrix is such that as the size of the matrix increases there is obtained a line to core ratio of 2:1, as compared to a square or rectangular matrix.
