DRAM

What is the main use of the DRAM standard called LPDDR?

  1. AExclusively for large servers
  2. BRecording on optical discs
  3. CDevices that require low power, such as smartphones
Show answer and explanation

Answer: C. Devices that require low power, such as smartphones

LPDDR (low-power DDR) is a mobile DRAM standard that reduces power with lower supply voltages, power-saving modes and other features. It is used in smartphones, tablets and thin laptops, and is sometimes stacked in the same package as the processor.
