ABSTRACT:
An electrically programmable memory array of the floating gate type is made by a process which allows the edges of the floating gates to be aligned with the edges of the control gates which also form address lines. Contacts to individual cells are not needed. These factors provide a very small cell size. The source and drain regions are formed prior to applying the first level polysilicon then covered with thick oxide, rather than using the polysilicon as a mask to define the gate areas.
