tors could be “least recently used” although they can not be replaced. Therefore, the “next
to be replaced sector” is the only sector whose lru bit is set and lock bit cleared. The ex-

“least recently used”, in which case there is no “next to be replaced sector” because no
sector will be replaced until at least one sector is unlocked.
