Scientists from Lancaster University report that we are close to combining SSD and RAM in one cell. “UltraRAM”, as it is called, is described as a memory technology that “combines the non-volatility of a storage memory data, such as flash, with the speed, energy efficiency and durability of working memory, such as DRAM.” 
The researchers report in detail their discovery in a recently published work.
The fundamental science behind UltraRAM technology is that it uses the unique properties of composite semiconductors, commonly used in photon devices such as LEDs, lasers and infrared detectors that can now be mass-produced.
The upcoming UltraRAM will offer "data storage times of at least 1.000 years." The fast data switching speed, and endurance in cclickerasures will be "a hundred to a thousand times better than flash drives". Add these qualities to the speed, energy efficiency and durability that DRAM has. So the new type of memory will be very hard for technology companies to ignore.
UltraRAM envisions breaking the gap between RAM and storage. So, in theory, you could use it as a solution to meet very distinct requirements. In a system computer, that will signalthat with an UltraRAM, say at 2 TB, you will be able to meet your RAM needs as well as your storage needs.
