Energy Optimization of the Memory Sub-System

Abstract

Memory is required to support computation. In the early days of digital computing, researchers focused on memory size optimization. Memory was expensive, and memory space was a scarce resource. The fast growth of semiconductor technology and the consequent increase of the level of integration has completely changed this picture. Nowadays, the cost per memory bit is extremely low, and memory size is rarely the main issue. Memory performance and power consumption are now the key challenges in system design.
