Xotiraning oqishi xotira ajratilganda va foydalanilgandan keyin bo'shatilmaganda yoki xotira ajratish ko'rsatkichi o'chirilganda yuzaga keladi va bu xotirani endi ishlatib bo'lmaydi. Xotiraning oqishi peyjingning ortishi tufayli unumdorlikni pasaytiradi va vaqt o'tishi bilan dasturning xotirasi tugashiga va ishdan chiqishiga olib keladi.
