Read-only memory device
 A read-only memory device comprises a plurality of groups of bit lines (BL.sub.0, BL.sub.1, . . . , BL.sub.63). One bit line within each group is selected by first column address decoders (4-1) and one group is selected by second column address decoders (8-0.about.8-3). One load element (Q.sub.L0, Q.sub.L1, Q.sub.L2, Q.sub.L3) is provided in each second column address decoder to pull up the potentials of the bit lines.
