Abstract

Semiconductor memory devices may include a write transistor including a first write gate controlling a first source/drain terminal and a second write gate controlling a channel region, and a read transistor including a memory node gate connected to the first source/drain terminal of the write transistor. The first write gate may have a first work function and the second write gate may have a second work function different from the first work function. The first source/drain terminal of the write transistor may not have a PN junction.
