摘要: A printed read only memory (ROM) device that consists of an array of memory resistors, a reference resistor, and analog-to-digital circuit is disclosed. Resistance values are dependent on the data to be stored in the read only memory. During read operation, a resistor in the array is powered, activating a voltage divider between the powered resistor and the reference resistor. The analog-to-digital circuit will read the divided voltage level between the two resistors, compare the voltage supply level and interpret it into bits of memory data. During the manufacturing of the ROM circuit, an array of memory resistors is printed as the means for storage of the data. Resistive inks of specific resistance values are selected and printed in a preferred layout that includes a reference resistor coupled to the determined array of memory resistors and an analog to digital converter so as to form a read only memory with the received data.
