Topic & Abstract:
Low Power DRAM Evolution
Low Power DRAM has evolved from a lower-voltage, lower-performance version of PC-DRAM designed for mobile packages to become one of the highest bandwidth-per-pin types of DRAM available. Along with this trend, the mobile system limitations now include active battery life and thermal limits in addition to standby battery life. This change in system limitations affects the choice of future LPDRAM architectures, beginning with the evolution of the LPDDR4 standard. Power efficiency across a range of bandwidths will become a more important attribute than raw peak bandwith. This presentation will investigate some proposed and alternative architectures and power saving techniques. |
