Abstract
A flash EPROM array ( ) and method of manufacture is disclosed. Source regions ( ) are shared between the memory cells ( ) of row ( ) pairs, and are isolated from one another in the row direction by isolation regions . Low resistance source conductor members ( ) extend in the row direction and are formed over the source regions ( ) and make contact therewith in a self-aligned fashion. The architecture allows for source decoding and thus enables user programmable sector erase architecture.
