This paper looks at the evolution of the "Memory Wall" problem over the past decade. It begins by reviewing the short Computer Architecture News note that coined the phrase, including the motivation behind the note, the context in which it was written, and the controversy it sparked. What has changed over the years? Are we hitting the Memory Wall? And if so, for what types of applications?
