What is Memory wall?
The problem that memory bandwidth and latency improve more slowly than processor performance, limiting overall performance. HBM, larger caches and advanced packaging are used to address it.
Field: DRAM
Memory wall in the explanations
Processor performance at times grew more than 50% per year, but DRAM access latency has stayed at tens of nanoseconds, leaving CPUs waiting hundreds of cycles for data—the memory wall.

Questions that mention Memory wall (2)
- What is the performance limitation called that arises because improvements in memory bandwidth and latency have not kept up with improvements in processor performance?
- What is the problem called in which the speed of supplying data from memory cannot keep up with improvements in processor compute performance, limiting overall performance?
