摘要:
A cross point EPROM array has trenches to provide improved isolation between adjacent buried N+ bitlines at locations where the adjacent buried N+ bitlines are not separated by a FAMOS transistor. This results in improved leakage current, improved punchthrough voltage characteristics, and in improved programmability for the cell.
