A diode matrix is a specific physical setup, a grid of wires used for implementing read-only memory. In this two-dimensional wire grid, each connection or intersection of wires either has a connecting diode, or an isolated design.
Techopedia explains Diode Matrix
Diode matrices have been used as control stores in various types of computers and electronic devices. A diode matrix was a common type of memory store architecture in early computers. It has also been used in items like programmable calculators. A diode matrix can be part of a programmable logic array chip. Some of these types of wire designs are still used in modern microprocessors.
