Emerging memories

Which correctly describes the position of 'storage-class memory'?

  1. AA non-volatile memory that bridges the gap in speed, capacity and cost between DRAM and NAND flash
  2. BRegisters inside a CPU
  3. CA type of optical disc
Show answer and explanation

Answer: A. A non-volatile memory that bridges the gap in speed, capacity and cost between DRAM and NAND flash

DRAM is fast but volatile and costly per bit, while NAND flash is non-volatile and cheap but slow. Non-volatile memory that fills the gap between them is called storage-class memory, and products using phase-change memory and similar technologies have been developed.
