Read-only memory circuit

Claim 2

A read-only memory circuit for reading a read-only memory card with a read-only memory card reader, comprising: a. a read-only memory card reader having a second nonconductive supporting substrate, a matrix of source electrodes attachably disposed on said second nonconductive supporting substrate, a matrix of drain electrodes attachably disposed on said second nonconductive supporting substrate in close alternating arrangement with said source electrodes, and semiconductor material attachably disposed between said source electrodes and said adjacent drain electrodes; b. a read-only memory card in register with said read-only memory card reader having a first nonconductive supporting substrate, a coded array of gate electrodes attachably disposed on said first nonconductive supporting substrate, and a dielectric coating covering said coded array of gate electrodes in contact with said matrix of thin semiconductor material, the gate electrodes being in registration with said matrix of thin semiconductor material; c. a set of first copper conductors, each connecting a row of the matrix of source electrodes; d. a set of second copper conductors, each connecting a column of the matrix of drain electrodes; e. a set of source electrode switches, each connected to a first copper conductor; f. a set of drain electrode switches, each connected to a second copper conductor; g. a set of ammeters, each connected to a source electrode switch; h. a source-drain voltage battery connected between the connected ammeters and the connected drain electrode switches; and i. a gate voltage battery connected between the connected ammeters and the coded array of gate electrodes so that a source-drain current will flow between a source electrode and a drain electrode when its corresponding source electrode switch and drain electrode switch are closed if a gate electrode exists thereabove and through the corresponding ammeter connected to said source electrode switch.
