             Appeal No. 1999-0045                                                                                   
             Application 08/688,235                                                                                 

             dependent claims within any of the above-stated rejections, including the separately stated            
             rejections of claim 23 identified as rejections 3 and 4 below and the rejection of claims 16-          
             18 and 24-26, identified as the seventh  rejection, we sustain the rejection of each of these          
             claims as well.                                                                                        
                    At the outset, we note that each of the respective four references relied upon by the           
             examiner are variations upon prior art flash memory systems of the same assignee of the                
             present application.  The examiner asserts for each of the stated rejections 1, 2, 5 and 6             
             argued by appellants that it would have been obvious for the artisan to have improved upon             
             the flash memory device of the base reference in light of the secondary and tertiary                   
             references.  We agree.  Since appellants have not contested this combinability, we agree               
             with the examiner's reasoning for it particularly in light of the examiner's additional                
             embellishments provided for all rejections at pages 19-21 of the answer.                               
                    Turning to the first stated rejection relying upon Fandrich '256, we note that this             
             reference does not contain any particular teachings or showings of an oscillator or synch              
             circuit within or related to the interface circuit 40 in Figures 3 and 4a of this reference.  We       
             embellish upon the examiner's reasoning by noting at the bottom of column 8 beginning at               
             line 58 that the flash memory device of Fandrich '256 may be commanded to enter a                      
             shutdown operation to enter into a standby mode for reducing power consumption to the                  
             extent broadly recited in the preamble of each independent claim on appeal.                            
             Correspondingly, Fandrich '300 has significant teachings of powering up and powering                   

                                                         4
