    摘要: Floating-gate field-effect transistors or memory cells formed in isolated wells are useful in the fabrication of non-volatile memory arrays and devices. A column of such floating-gate memory cells are associated with a well containing the source/drain regions for each memory cell in the column. These wells are isolated from source/drain regions of other columns of the array. Fowler-Nordheim tunneling can be used to program and erase such floating-gate memory cells either on an individual basis or on a bulk or block basis.
