Hemispheric dissociation in mnemonic processes is suggested by the Hemispheric Encoding\Retrieval Asymmetry (HERA) model (e.g., Nyberg, Cabeza, & Tulving, 1996):

I'm not sure how popular these claims are nowadays...  

Here is a potentially useful recent work:

You may want to look up the references listed in the paper too.

HERA was first proposed by Tulving et al. in PNAS 1994:
