DRAM and eRAM
Martin Brox, Kazuhiko Kajigaya · 2007
Demand growth for electronic systems has been driven by new consumer and computing applications. The most popular examples are the next-generation, high-resolution game-consoles. These systems heavily leverage the performance of today’s memories and processors. Yet, these applications are still unable to create a life-like experience due to the limitations of the on- and off-chip memory bandwidth available to the processing functions. Careful optimization of the memory hierarchy bandwidth is necessary to improve system performance. High-speed embedded-DRAM (eDRAM) has evolved as a serious contender to embedded-SRAM (eSRAM), while external datarates continue their rapid rise. However, speed improvements cannot stand on their own as system costs must be kept reasonable. To this end, good test and repair solutions reduce cost and facilitate higher levels of integration. The presentations in this session report recent advances that address these challenges.
