Questions and Answers

What is the main difference between SRAM and DRAM?

  • SRAM requires periodic refreshing, while DRAM does not. (correct)
  • SRAM is non-volatile, while DRAM is volatile.
  • SRAM stores each bit of data in a tiny memory cell, while DRAM uses a flip-flop circuit.
  • SRAM uses a capacitor and transistor for data storage, while DRAM uses a latch circuit.

    • How is data stored in SRAM?

  • In a capacitor and transistor
  • In a flip-flop circuit
  • In a latch circuit made of transistors (correct)
  • In a tiny memory cell

    • Which type of memory requires constant refreshing to maintain stored data?

  • ROM
  • SRAM
  • DRAM (correct)
  • Flip-flop memory

    • What is the main function of the transistor in DRAM?
