Abstract:
Lower saturation current flowing through the same cell twice is a major drawback of vertical stack array transistor architecture. A loading effect further reduces the saturation current and causes higher threshold voltage. A simple word line cut process not only doubles the bit density to reduce the bit cost, but also reduces the loading ...More
