DRAM

What is the performance limitation called that arises because improvements in memory bandwidth and latency have not kept up with improvements in processor performance?

  1. AMoore's law
  2. BSilicon cycle
  3. CMemory wall
Show answer and explanation

Answer: C. Memory wall

Processor computing performance has improved greatly, but DRAM access latency and bandwidth have not improved as much, so time spent waiting for data has come to limit performance. This is called the memory wall. Larger caches and high-bandwidth memories such as HBM are responses to it.
