Discontinuous nitride structure for non-volatile transistors

The present invention relates to multiple independent bit Flash memory devices, and more particularly with charge sharing in multiple independent bit Flash memory devices. A multiple independent bit Flash memory cell has a gate that includes a first oxide layer, a discontinuous nitride layer on the first oxide layer, a second oxide layer on the discontinuous nitride layer and the first oxide layer, and a polysilicon layer on the second oxide layer. The discontinuous nitride layer has regions residing at different portions of the layer. These portions are separated by the second oxide layer. Thus, with a smaller channel length, charge that otherwise would migrate from one region to the other and/or strongly influence its neighboring it is blocked/impeded by the second oxide layer. In this manner, the potential for charge sharing between the regions is reduced, and a higher density chip multiple independent bit Flash memory cells may be provided.
