满满的回忆应该怎么说英语

"Full of memories" is a good way to describe something that is filled with memories in English. You could also say "laden with memories" or "overflowing with memories." Here are some example sentences:
My grandmother's old photo album is full of memories from her childhood.
The attic was filled with old boxes, all overflowing with memories of my parents' youth.
The small, cozy cabin in the woods was filled with memories of our family vacations.
