memcahce is a general-purpose distributed memory caching system. It is used to speed up dynamic database-driven websites by caching data and objects in RAM to reduce the number of times an external data source (such as a database or API) must be read. This is very useful for CMS based sites like Joomla and Wordpress. Joomla has built-in caching system that can be configured to use memcache as the caching engine and it can be setup from Joomla system configuration, for wordpress you have to install a caching pluing that supports memcahce, a popular plugin is w3 total cache.
