We deal with computers all the time and do our different tasks, a computer consist of different hardware and among them Memory is one of the most important component of a computer, today I’ll be telling you guys if bios memory volatile or nonvolatile.
What is Memory? And what exactly we mean from volatile and non-volatile memory.
The first thing comes to mind of non-technical user is that what actually memory means in the field of computer science, by native dictionary memory is the faculty that saves information in brain and for a computer CPU is the brain and RAM is considered as its primary memory, I won’t be going in depth but RAM is Volatile memory that means once power cuts of everything in it will vanish. Hard Drives and other secondary types of memories are non-volatile which means data in them will remain there unless you delete it yourself, now coming to my main topic which is pretty simple.
Bios Memory Volatile or Nonvolatile?
Answer to this question “Bios memory is non-volatile” and the purpose of bios memory which is located on motherboard is to store bios settings but the story does not ends here, BIOS RAM is called as CMOS RAM due to the fact it’s using a volatile metal oxide semi-conductor yeah you heard it right “volatile” what really makes this memory non-volatile is a small battery that keeps it on all time. So actually you aren’t really cutting off the power that’s why all settings are kept save in Bios Memory, the CMOS memory don’t take much of the battery resources and remaining part is consumed by RTC(real-time-clock), standard NVRAM is about 512kbytes which is enough to store all bios settings. So in a way answer to bios memory volatile or nonvolatile? Is not that simple, its volatile and non-volatile at the same time.
