Recoding is the generic name of processes that take place after the original event and thereby bring about changes in the engram.  Recoding processes reflect the fact that memories tend to change over time.   Research in episodic memory has shown that reference to the original event after it has occurred can change what a person reports (or remembers)  about the original event.  There is current debate as to whether recoding modifies the original event or creates a new memory (the recoded engram).  In either case, the recoding process plays a critical role in what we remember -- and has significant implications for the legal system.
