Though you can write a byte to an 8 bit addr, and a word to a 16 bit addr.

If you do not have byte addressable memory but only want to change half a 
word of memory, are your performance constraints really so tight that a 
bitmask is not acceptable? E.g.
word &= 0x00ff;   /*Blank out the most significant byte.*/
word |= byte << 8;   /*Assign the value to the most significant byte.*/
/*Alternatively when the least significant byte is desired...*/
word &= 0xff00;
word |= byte;
