Structure and method for reducing charge loss in a memory cell

The present invention is generally related to the field semiconductor devices. More particularly, the present invention is related to memory cells in semiconductor devices. According to one exemplary embodiment, a structure comprises a first bit line and a second bit line. The structure further comprises a first memory cell situated over the first bit line, where the first memory cell comprises a first ONO stack segment, and where the first ONO stack segment is situated between the first bit line and a word line. The structure further comprises a second memory cell situated over the second bit line, where the second memory cell comprises a second ONO stack segment, where the second ONO stack segment is situated between the second bit line and the word line, and where the first ONO stack segment is separated from the second ONO stack segment by a gap. The first memory cell and the second memory cell may each be capable, for example, of storing two independent data bits.
