Abstract
Disclosed is a method, system, and program for caching data. Data from a device, such as a volatile memory device or non-volatile storage device, is maintained in entries in a cache. For each entry in cache, a variable indicates both a time when the cache entry was last accessed and a frequency of accesses to the cache entry.The variable is used in determining which entry to denote from cache to make room for subsequent entries.
