Do I need strong mathematical bases to work in the memory subsystem?

I wouldn't call that C code basic.  Regardless, showing an example of a
driver that doesn't need math, and it might if you understood the high
level math, and your not aware of it, but predictive branching would
need it.  You can not calculate simple interest efficiently without
calculus.  This repeadely ends up being an issue of "if I don't know it,
I don't need it", which is wrong.  More math helps you every time.  Math
is advanced logic.  I can't tell you how many times I see folks brute
force their way to solutions that they should be using integration.
