technology bubble memory

As reports source, the technology bubble memory , about prospects for which much spoke in 1970- years, can find a new use in logical IS.
I will allow itself brief excursus into the history: bubble memory was proposed by colleague Bell Andrews's Labs in 1967 as the two-dimensional version of the memory unit Of twister (using effect of magnetostriction), in which besides the magnetostriction was used the effect of shaping microscopic circles (phials) of orthoferrite or Permalloy on the special surface (for example, pomagranate), whose size was repeated less than the sizes of magnetic bubbles on the film, already received wide application in the cassettes and the bobbins for the record audio. This, in turn, gave hope for the creation of the energy-independent devices of higher density and the group Of bobeka created ZU with the area 1 sq. cm, on which were accommodated 4096 data bits. In the middle 1970- X years broke out the present boom of interest in the bubble technology of â€“ almost all chief producers they worked at the commercial introduction of bubble memory, in particular, Intel even let out [megabitnyj] chip 7110. However, this boom rapidly ceased with the advent of on the market in 1980- e the years of the hard disks, which allowed higher density writing and speed with the much smaller price. However, and after this there were separate devices on the bubble memory â€“ the portable computer sharp PC 5000 (1983) and the game prefix Of konami on the base Of z80, but work in the direction the developments of bubble ideas were subsequently ended.

And here, after thirty years, in Massachusetts Institute of Technology again propose to use magic phials, but no longer ferromagnetic material, but the liquids. If it is more precise than â€“ of micro-liquid (microfluids). How it is possible to understand, the discussion deals with using of microscopic amounts of liquid for coding data â€“ phial indicates 1, its absence â€“ 0 . This technology was developed for laboratory-on- chip - modifications the system-on- chip, optimized for the chemical, biological or medical tests. Using the approach proposed by scientists, not possible only the conducting of tests, but also chemical reactions with negligibly small quantities of substance â€“ from one nano-liter solution, moreover the course of reactions can be programmed with the aid of those phials themselves, situated in the microscopic channels laboratory-on- chip.

Possibly even programming of computational operations is, however, thought with the aid of such phials that the mentioned today quantum computers will manage the computational task nevertheless more rapid and more effective. Therefore, most likely, this completely curious old technology it is judged to remain only in the narrow to the circle of scientific research and biomedical sphere of application.
