....Disk Cache Flash memory has two advantages and one disadvantage over DRAM as a disk cache. The advantages are nonvolatility and lower power consumption; the disadvantage is poorer write performance. Thus, flash memory might be effective as a second level cache below the standard DRAM disk cache [19]. At that level, most writes would be flushes from the first level cache, and thus asynchronous. However, using memory with such different characteristics necessitates novel cache management strategies. The main problem with using flash memory as a secondlevel cache is that data cannot be ....
....a secondlevel cache is that data cannot be overwritten without erasing the entire segment containing it. One solution is to ensure there is always a segment with free space for writing; this is accomplished by periodically choosing a segment, flushing all its dirty blocks to disk, and erasing it [19]. One segment choosing strategy is to choose the one least recently written; another is to choose the one least recently accessed. The former is simpler to implement and ensures no segment is cleaned more often than another, but the latter is likely to yield a lower read miss ratio. Unfortunately, ....
