Memory bandwidth refers to the amount of information accessed by the memory in unit time, also known as the number of bits or bytes read/written by the memory in unit time.
Memory bandwidth, reflecting technical indicators of data transmission rate (unit: bps, bit per second, bit/s, or Bytes/s, byte/s)
The bandwidth of the memory determines the transmission speed of the information obtained by the memory centric machine, which is a key factor to improve the bottleneck of the machine.

In order to improve the memory bandwidth, the following measures can be taken:
We usually use bandwidthIndicates that if the storage cycle is, each read/writeBytes, then its bandwidth。asAccess cycle500ns, each access cycle can access 16 bits, so its bandwidth is 32M bits/s
