   I always regard memory as a grid. The address is vertical, and the bit   
   position is horizontal.

   That's an artefact of humans using decimal, and computers using bytes -   
   you're treating it as a BCD number.   
      
   1234 read least-significant first is 0x4d2. In LSB-first memory that's   
   one byte of D2, and another of 04.   
      
   In memory it's   
   11010010   
   00000100   
      
   (or possibly   
   01001011   
   00100000)
