US researchers said that they use carbon nanotubes instead of silicon as a raw material, so that memory and processor stacked together in three-dimensional manner, reducing the time between the two data, which greatly increased the processing speed of the computer chip, the use of this Method developed by the 3D chip speed may reach 1000 times the current chip.

One of the researchers, Max Shalakir, Stanford University PhD candidate in electrical engineering, explained that the stumbling block to the speed of computers is that the data takes a lot of time and energy to switch back and forth between the processor and the memory. However, solving this problem requires skill. Memory and central processing unit (CPU) can not be placed on the same wafer, because the silicon-based wafer must be heated to about 1000 degrees Celsius; and many hardware components in the hardware are melted at this high temperature.

To this end, Charalaker and mentor Sabbath Mitra and others who have turned their attention to the carbon nanotubes. Chalackel said that carbon nanotubes have the characteristics of light weight, perfect hexagonal structure connection, can be processed at low temperatures, compared with the traditional transistor, the smaller, more conductive and can support fast switching, so Its performance and energy performance is much better than traditional silicon materials.

However, the use of carbon nanotubes manufacturing chips is not easy. First of all, the growth of carbon nanotubes is very poor control; Second, there is a small amount of metallic carbon nanotubes will damage the performance of the entire chip. Researchers find ways to solve these problems and in 2013 created the world's first carbon nanotube computer. However, this computer is both slow and heavy, with only a few transistors.

Now, the researchers went one step further and developed a way to pile up memory and transistors. The new 3D design approach drastically reduces the "commute" time between data and transistors and memory, the computational speed of new structures 1000 times for the existing chip. Moreover, the research team also utilizes the new chip architecture to develop multiple sensor wafers that can be used to detect infrared light, specific chemicals, and more. Next, they intend to upgrade the system to create larger and more complex chips.

The evolution of electronic components has never ceased, and as they become smaller, more powerful, and less expensive, scientists have never stopped pursuing speed. Two years ago, a research team at Stanford University developed the world's first computer based on carbon nanotube manufacturing and took the first step in challenging the mainstream silicon-based computer materials. Two years later, Scientists make this chip a fashionable 3D carbon nanotube computer chip, we can not help but lament the imagination of scientists, and even the new stacking method can make computer chips up to 1000 times the speed, you must manually click a thumbs up!
