Recently, researchers from the University of Washington and Microsoft are conducting research on biological storage, hoping to meet the growing demand for storage through biological DNA. At present, the storage potential of DNA is also being continuously developed and exploited. Is the so-called “biological storage” expected to replace semiconductors as the basis of computer industry in the future?
With the continuous development of computer technology, semiconductor related technologies and industries are also constantly improving. At present, the semiconductor industry in the world has basically formed a complete global ecological chain, which is basically controlled by the United States, Japan, South Korea and Taiwan. From the original Bell lab to today’s semiconductor pattern, it is true that the reform and development of the semiconductor industry has not stopped for decades. However, with the increasing demand for hardware of intelligent devices, as well as the storage requirements of various artificial intelligence products and big data, the development speed of semiconductor has met the development speed of the Internet 。
In addition to its own speed of development, the gradual failure of Moore’s law also gradually makes this situation more serious. In the early days of the development of the semiconductor industry, Moore’s law has been constantly verified, but recently, the development speed of the semiconductor industry has gradually slowed down, which may reach the development bottleneck in a period of time in the future. Biological storage may take over the task of computer storage and start to change the Internet era.
By using DNA amino acids and other biological molecules are very complex and can support the programmable characteristics, researchers have developed the corresponding software, that is, the interpreter of DNA storage content. By converting the binary codes of 0 and 1 in our computer language into a, G, C, t of DNA base, it is equivalent to an interpreter of storage program, so that DNA can be divided into two parts As we all know, it is the foundation of the development of computer technology.
And through such an interpreter to achieve the function of reading interpretation, then how to read in the data? This is actually much simpler than developing the corresponding algorithm and software, because the automatic editing and generating technology of DNA has been mature for a long time, and the cost is low, so it is not too difficult to read the data. At present, from the theoretical level, 1 g of DNA molecules can store about 2 million TB of data. Compared with the size and capacity of the current hard disk, the storage efficiency of biological molecules is undoubtedly far beyond the current.
However, at present, such a storage method is still in the stage of laboratory development. The manufacturing cost is very high, far from cost-effective, and the practicability is basically zero. The time limit of semiconductor industry has not really arrived. The development of biological semiconductor also needs the continuous development and cooperation of related industries and Science, so as to reduce the cost of the industrial chain and improve the relevant Application scenarios, into ordinary people’s homes. At that time, perhaps “one kilogram of DNA stores global information” will really become a reality.
