         Appeal No. 95-2665                                                         
         Application 07/999,609                                                     


         unconvinced that the artisan would have done so from the                   
         rationales expressed by the examiner and/or the teachings of               
         each of these references.                                                  
              This indirectly relates to the argued position from                   
         appellant that a three transistor structure is disclosed.  It may          
         be disputed as to the detail in which this feature is indirectly           
         recited in each independent claim on appeal, yet Guterman does             
         set forth an equivalent three transistor structure in Figures 1-           
         2.  This is the only reference from which we can clearly discern           
         that a three transistor structure is taught and/or suggested.              
         The other references appear to teach either one and/or two                 
         transistors.  This is critical to an understanding of the overall          
         structure of each independent claim on appeal as a starting point          
         because the simultaneity of the accessibility of each cell in the          
         functional wherein clause is based upon the substantial                    
         simultaneous energization of the claimed first and second traces.          
         As dis-closed, this activates the middle transistor in                     
         representative Figure 5 of the disclosed invention.  This we are           
         urged would be done effectively in Guterman, but we remain                 
         unconvinced of the simultaneity in that reference alone even as            
         modified by the single and/or double transistor teachings in               
         Hasunuma, Komori and Ma.                                                   

                                         7
