Install this if you are using Memcache... you are using Memcache or something besides the DB, right??? From the project page:
"Entity cache puts core entities into Drupal's cache API.
Due to the entity loading changes in Drupal 7, no core patches are required.
Don't bother using this module if you're not also going to use http://drupal.org/project/memcache or http://drupal.org/project/redis - the purpose of entitycache is to allow queries to be offloaded from the database onto alternative storage. There are minimal, if any, gains from using it with the default database cache."
