Abstract
When performing a consolidation process, entries (uRuns) in the update region (uRegion) of an update layer (uLayer) are typically erased immediately after the data in the uRuns is updated to a master layer (mLayer). The data may, at a later time, be copied back to the uRuns for read purposes. Rather than erasing the uRuns and then copying the data back to the uRuns for read purposes, the uRuns can simply not be erased after the consolidation. If space is needed, the uRuns can be erased without any need for consolidation. Furthermore, if another consolidation process occurs, the uRuns that were previously consolidated, but not erased, can simply be erased.
