<p>A printed read-only memory (ROM) device (136) that consists of an array of memory resistors (210), a reference resistor (220), and an analog-to-digital circuit (240) is disclosed. Resistance values are dependent on the data to be stored in the read-only memory. During read operation, a resistor (210) is powered, activating a voltage divider between the powered resistor (210) and the reference resistor (220). The analog-to-digital circuit (240) reads the divided voltage level between the two resistors (210, 220), compares it to the voltage supply level, and interprets it into bits of memory data.</p> |
