Abstract
A read-only memory (ROM) cell has first and second transistors connected in series between a true bit line and a voltage reference (e.g., ground), and third and fourth transistors connected in series between a complement bit line and the voltage reference. The gates of the first and third transistors are connected to a first word line, and the gates of the second and fourth transistors are connected to a second word line. The ROM cell is programmed to store any possible combination of two bits of information by appropriately (i) connecting the node between the first and second transistors to either the true bit line, the complement bit line, or the voltage reference and (ii) connecting the node between the third and fourth transistors to either the true bit line, the complement bit line, or the voltage reference.
