  • 8. Which memory is non volatile and may be written only once?
  • filter_dramaExplanation
    Answer is : D
    A programmable read-only memory (PROM) or field programmable read-only memory (FPROM) or one-time programmable non-volatile memory (OTP NVM) is a form of digital memory where the setting of each bit is locked by a fuse or antifuse. It is one type of ROM (read-only memory). The data in them is permanent and cannot be changed. PROMs are used in digital electronic devices to store permanent data, usually low level programs such as firmware (microcode).
  • 9. The memory which is programmed at the time it is manufactured is
  • filter_dramaExplanation
    Answer is : B
    None.
  • 10. Which of the following memory is volatile
  • filter_dramaExplanation
