Does Malloc get memory from RAM or cache

I have a Native android app which Makes a lot of calls to Malloc. I am trying to allocate a chunk of the RAM and then run some memory intensive tasks to see how my Android device handles it. But I am not sure if the device is taking memory from the RAM or other sources of memory. Is there a way to find out? If it is taking memory from the cache, how do I make it so I am allocating the memory only from the RAM?

malloc() allocates memory from the process' heap, which in turn comes from the device RAM. It has done so for decades.
