DRAM

What is the main purpose of dividing the inside of a DRAM into multiple banks?

  1. ATo reduce capacity
  2. BTo overlap operations in different banks and improve effective access performance
  3. CTo increase heat generation
Show answer and explanation

Answer: B. To overlap operations in different banks and improve effective access performance

Activating and precharging a DRAM row takes time. With multiple banks, one bank can be accessed while another performs these operations, hiding the wait time and improving overall transfer efficiency.
