A nitride read only memory cell comprising a silicon-germanium layer with a pair of source/drain regions. A strained silicon layer is formed overlying the silicon-germanium layer such that the pair of source/drain regions is linked by a channel that is generated in the strained silicon layer during operation of the cell. A nitride layer is formed overlying the substrate. The nitride layer has at least one charge storage region. The nitride layer may be a planar layer, a planar split gate nitride layer, or a vertical split nitride layer. A control gate is formed overlying the nitride layer. Ballistic direct injection is used to program the memory cell. A first charge storage region of the nitride layer establishes a virtual source/drain region in the channel. The virtual source/drain region has a lower threshold voltage than the remaining portion of the channel.
