Differential Read-Only Memory (ROM) Device

A read-only memory (ROM) device includes a memory cell that is electrically coupled to a bitline (BL) or to a BL which represents a complement of the BL. The ROM device precharges the BL and the BL to a first logical value. The ROM device activates the memory cell which discharges the BL when the memory cell is coupled to the BL or discharges the BL when the memory cell is coupled to the BL. The ROM device reads the first logical value as being stored within the memory cell when the BL is less than the BL. Otherwise, the ROM device reads the second logical value as being stored within the memory cell when the BL is greater than the BL.
