A compact memory has a plurality of memory cells that are serially coupled. The plurality of cells are capacitively coupled to a substrate and directly coupled to switching circuits at both of its ends, which can disconnect the plurality of cells from a bit line at one end and a ground bus at the other...http://www.google.com/patents/US4933904?utm_source=gb-gplus-sharePatent US4933904 - Dense EPROM having serially coupled floating gate transistors
