Structures and methods for write once read only memory employing floating gates are provided. The write once read only memory cell includes a floating gate transistor formed in a modified dynamic random access memory (DRAM) fabrication process. The floating gate transistor has a first source/drain region, a second source/drain region, a channel region between the first and the second source/drain regions, a large work function floating gate separated from the channel region by a gate insulator, and a control gate is separated from the floating gate by a gate dielectric. A plug is coupled to the first source/drain region and couples the first source/drain region to an array plate. A transmission line is coupled to the second source/drain region. The floating gate transistor can be programmed in two directions to trap charge in the high work function floating gate.
