Abstract

An accidental access memory cell arrangement coupled by electric charge comprising a semiconductor body having therein an impurity of a first type of conductivity, a first bit line region of said semiconductor body having in it an impurity of the type of opposite conductivity, a second gate region of said semiconductor body adjacent to said first region and having a predetermined threshold voltage, said second region therein having an impurity of said first type of conductivity and a concentration greater than the impurity of said semiconductor body, a third storage region of said semiconductor body adjacent to said second region and having a threshold voltage lower than said predetermined threshold voltage of said second region, and a single electrode extending in superposed relationship with said second and third regions of said semiconductor body.
