The major leakage paths in a DRAM cell stem from reverse junction leakage from the storage node, and gate induced drain leakage (GIDL) current. Empirically it is known that the junction leakage is affected by the lateral electric field near the storage node, which is enhanced by an increase in substrate doping due to threshold adjustment.

Current leakage is among the most frequent faults that afflict modern electrical devices. This leakage can show itself in a variety of ways; some devices may function normally yet consume a lot of power, while others may stop functioning altogether. This is partially because there are so many various ways current leakage can happen. For […]
