Detailed Description

The Sync operation unifies several partial memory blocks.

These blocks have to be pairwise disjunct or the values in common locations have to be identical. This operation allows to specify all operations that eventually need several partial memory blocks as input with a single entrance by unifying the memories with a preceding Sync operation.
