Topic: Computer Organization

Which one of the following statement is not true for static random access memory (SRAM)

  • A. Static RAM stores data in the form of charge
  • B. They have low capacity, but offer high speed
  • C. It doesn't require periodic refreshing
  • D. They are made up of six CMOS transistor

Answer: A. Static RAM stores data in the form of charge

Explanation: Static RAM (SRAM) uses bistable latching circuitry (made up of transistors, typically 6 per cell) to store each bit, not capacitors. Dynamic RAM (DRAM), on the other hand, stores data in the form of charge on a capacitor and therefore requires periodic refreshing. Thus, the statement that SRAM stores data in the form of charge is incorrect.
