What are bitwise shift (bit-shift) operators and how do they work?
... of two that added together makes 320:
(row * 320) = (row * 256) + (row * 64)

(row * 320) = (row << 8) + (row << 6)
For a final result of:
memoryOffset = ((row << 8) + (row << 6)) + column
Now we get the same offset as before...
