diode matrix meaning

• [Electronics]
  In some digital devices, a grid of wires, the intersections of some being interconnected through diodes, whose polarities determine circuit operation. A series of AND circuits is provided by this arrangement, which acts as a high-speed rotary switch when it is supplied with input pulses.
  

• Current steering diode matrix
• Before integrated circuits, other firmware devices included a discrete semiconductor diode matrix.
• A diode matrix is used as the control store or microprogram in many early computers.
• Some modern microprocessors and application-specific integrated circuits ( ASICs ) use a diode matrix or transistor matrix control store.
• :A diode matrix ROM has multiple address lines, each of which is connected to a number of output lines using diodes.
• Each step of the clock selected one or more signal lines in a diode matrix that enabled gates and other circuits on the machine.
• Here is a historical example of one diode matrix ROM panel .-- talk ) 06 : 17, 28 January 2009 ( UTC)
• The " blank " PLA from the chip manufacturer came with a diode matrix or transistor matrix with a diode ( or transistor ) at every intersection.
• DEC later added an optional diode matrix read-only memory for the PDP-11 that stored a bootstrap program of up to 32 words ( 64 bytes ).
• Strictly, " read-only memory " refers to memory that is hard-wired, such as diode matrix and the later mask ROM ( MROM ) which cannot be changed after manufacture.
