Abstract
A dynamic random access memory. The memory includes a write transistor N3 and a read transistor N2. In a preferred embodiment the write transistor has a threshold level higher than the read transistor. A sense amplifier senses and amplifies a difference in voltage between a bit line and a sense node that is developed when the read transistor permits or does-not permit current to flow between ground an a bit line. Associated semiconductor device structures and fabrication techniques are also disclosed.
