Volatile memory tends to run faster than non-volatile memory. That is why computers use volatile memory for tasks that require fast response times and need memory for only small intervals of time. Non-volatile memory tends to be slower because it has to write and record the data so that users can call on it again. Non-volatile memory and volatile memory differ in functionality within a system.

To make matters more concrete, let's suppose thread A writes to a volatile variable, and then thread B reads the same volatile variable. Volatile memory or random access memory stores information such as running process, incognito browsing sessions, clipboard data , information stored in plain text files and much more. In case of any malware attack or suspicious activity, capturing volatile memory becomes essential as it stores the running process and services information.

Volatile Memory is a type of memory who continuously needs power connection to function. When the computer’s power is turned off, volatile memory loses its contents. And the information will get erased when the source is out. The most common and well known form of Volatile Memory we are using in our computers is Random Access Memory (RAM). Non-volatile memory is computer memory that can retain the stored information even when not powered. Examples of non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

asm volatile("": : :"memory") is often used as a memory barrier (e.g. as seen in the Linux kernel barrier macro). This sounds similar to what the GCC builtin __sync_synchronize does. Are these two 2021-03-14 · Unlike volatile memory, NVM does not require its memory data to be periodically refreshed. It is commonly used for secondary storage or long-term consistent storage. Non-volatile memory is highly popular among digital media; it is widely used in memory chips for USB memory sticks and digital cameras.

Main memory or RAM uses volatile memory. volatile int *foo = some_memory_mapped_device; while (*foo) ; // wait until *foo turns false Without the volatile specifier, the compiler is allowed to completely optimize the loop away. The volatile specifier tells the compiler that it may not assume that 2 subsequent reads return the same value. Note that volatile has nothing to do with threads.
