Earlier the memories used to have more speed than the processors. But with the invention of microprocessors and microcontroller the speed of the memory has become lesser than these processors. So with the improvement of microprocessor these years, the memory access time has been a bottleneck which limits the system performance. Even though the system has high frequency every application needs to access the memory several times and the memories have lesser speed than the processor. So the memory accessing time definitely limits the system performance.
