 ## Remarks  
- If the cache size exceeds the specified limit, the memory cache implementation removes cache entries.  
+ If the total amount of physical memory in use on the system exceeds the specified limit, the memory cache implementation removes cache entries.  
   
  The setting for the <xref:System.Runtime.Caching.MemoryCache.PhysicalMemoryLimit%2A> property can be read from `physicalMemoryLimitPercentage` configuration attribute in the application configuration file. Alternatively, the value can be passed when the <xref:System.Runtime.Caching.MemoryCache> class is initialized.
