Y Diode Matrix

This document describes the G614 module, which contains 256 diodes configured as an 8 x 8 two-way crosspoint switching matrix. This matrix provides 64 interconnecting points. Sixty-four cores from each of the 18 memory planes are connected between these pairs of points, establishing the current paths for the Y axis within the core memory stack. Users are directed to engineering drawings D-BS-MM15-0-6 and D-BS-MM15-0-7 for further details.
