What's the reason to have such a low number of bits (only 8 bits) on the data pin when the row buffer we are loading is as big as 2kbits?

@mpcomplete, the row buffer is 2Kbits here, but the transfer comes from selecting a column from the row and transferring it. Most of the row buffer is untouched on this operation, but a subsequent one may select a different column and transfer it. Just as processor caches are much smaller than DRAM, they are only accessing and transferring over these small portions of the data.
