Can I do MOVX to external serial SRAM?

The operation of the MOVX instruction is clearly defined in the 80C51 family programmer’s guide and instruction set document - which is chapter 2 of the so-called "bible" for the 8051:

Need more Internal RAM            01/01/70 00:00      
   Yes, but they handle it the same as external RAM            01/01/70 00:00      
   Look here            01/01/70 00:00      
      Ok            01/01/70 00:00      
   complicated and complicated            01/01/70 00:00      
   why?            01/01/70 00:00      
   It's Not Really So Complicated--And....            01/01/70 00:00      
      someone recently posted a link to a 805x with 64kB of RAM            01/01/70 00:00      
      Proper methodology can't really bound the memory requirement            01/01/70 00:00      
      That's My Point            01/01/70 00:00      
   RAM expansion need not be complicated!            01/01/70 00:00      
      MOVX problem            01/01/70 00:00      
         No            01/01/70 00:00      
            unless you have external glue logic            01/01/70 00:00      
               Yes            01/01/70 00:00      
         "bible" time!            01/01/70 00:00      
      There are much larger SPI memories            01/01/70 00:00      
   Look at Wiz chip            01/01/70 00:00      
      Link?            01/01/70 00:00      
         links            01/01/70 00:00      
            Overkill?            01/01/70 00:00      
               and expensive?            01/01/70 00:00      
                  When at electronics store            01/01/70 00:00      
                     Which one?            01/01/70 00:00      
                     How does that compare with ordering from outside?            01/01/70 00:00      
                        I've always had to do that!            01/01/70 00:00
