Although SSDs have and continue to make drastic improvements in data access times, RAM thus far remains the faster type of memory, typically referred to only as memory, inside devices.

RAM, however, is volatile memory. Unlike non-volatile memory found in hard drives and flash drives, data stored in RAM is kept there temporarily, only for as long as there is an electrical current being provided to the chips.
