Editing Memory hierarchy (section)

==Properties of the technologies in the memory hierarchy==
* Adding complexity slows the ''memory hierarchy''.<ref>[[Write-combining]]</ref>

* Latency and bandwidth are two metrics associated with caches. Neither of them is uniform, but is specific to a particular component of the memory hierarchy.<ref name=sun>{{Cite journal  | first = Ruud  | last = van der Pas  | title = Memory Hierarchy in Cache-Based Systems  | url = http://www.sun.com/blueprints/1102/817-0742.pdf  | year = 2002  | page = 26  | place = Santa Clara, California  | publisher = [[Sun Microsystems]]  | id = 817-0742-10}}</ref>
* Predicting where in the memory hierarchy the data resides is difficult.<ref name=sun />
