Abstract
An encoded ROM array structure couples a first one of a first set of bitlines to a second one of a second set of bitlines through a transistor when the wordline connected to the gate terminal of that transistor is asserted. This encoded arrangement can be extended to any number of encoded bitlines, e.g., 2, 4, 8, 16, and so on. Each of the first plurality and second sets of bit lines are coupled to circuits for charging and discharging the bitlines. To read data from the first set of bit lines, the second set of bitlines is discharged, and vice versa.
