What does constructive memory relates to dissociative identity disorder?

Interesting question: Memory is very limited and often a dynamic and changing process. We remember only a small fraction of what we experience. Think about how much you have seen and heard today, and how much real detail you can't remember! often our memories are constructed from our thoughts, dreams, and intentions in addition to "real" experiences. "did" may well involve constructed "memories" of alters.

Constructive memory: When remembering traumatic events, memory doesn't work like a vcr that can be played back later, verbatim. Instead you store an emotion-tinged experience in bits and pieces -- some of which may stand out more than others. When you later try to tell someone what happened, you are "constructing" the experience into story form, for understanding. This can make did patients' histories confusing.
