Electronic memory device performance declines with the rising of temperature, but the scientists put forward a new memory design, but need to be work under the high temperature of more than 600 open (About 327 ℃) .The nanometer thermal mechanical memory (Nano ThermoMechanical memory) using thermal instead of electricity, to record, store, and restore data, the future is expected to be applied in space exploration mission, deep well drilling, internal combustion engines and other fields.
Graduate student at the university of Nebraska Lincoln mahmoud al l card and west di er, assistant professor of recently published a paper just published in journal of applied physics letters, describes the new memory."(the study) is the most important significance lies in the actual design/developed a high temperature storage (logical) devices."Well said, "does not yet exist to keep good performance in extreme environment of random access memory."
On January 8, according to physicists organization network (Beijing time), in the new design of nano thermal mechanical memory, binary storage "0" and "1" is said by the temperature of the two kinds of stable state.In the simulation experiments, for example, 1038 on behalf of the "0", and 1341 on behalf of the "1".
Have two different kinds of steady state temperature are very rare, because most of the equipment only a stable temperature condition.To do this, the key is careful to control heat transfer between the minimal distance between two objects.In the new high temperature storage device, the two objects are: a fixed hot end and the lower part without a fixed temperature and lower the head (head)."Head" can be free to move up and down, and through a handle fixed with the bottom of another cold (simulated experiments for 600) connected to the terminal.desktop ddr3 ram 16gb
When heat is applied to hot terminal, some will by far field radiation heat transfer to the "head".As the temperature rise in the "head" spider elongation due to thermal expansion, and the "head" from the hot end of narrow spacing (similar to a radiation wavelengths), then the main mode of heat transfer into the near field rather than the far field radiation.What is important is that from the hot end to the "head" the heat transfer in actually increase, even if the temperature difference between the reduced.This counterintuitive phenomenon known as negative differential resistance (NDTR), the temperature of the two stable states and is therefore to exist.pc ddr3 4gb memory
When hot terminal (through the near field radiation) is passed to the quantity of heat of "head" and "head" (through) to connect the handle down conduction heat loss is equal, there will be a steady temperature state, also known as hot blocking state.If this state of affairs to be broken due to lower temperature, the system will automatically get heat to return to stability;Conversely, when the temperature increases, it will automatically heat loss.Under two kinds of stable temperature in the middle of the as the critical state, if higher than the critical value, the system will tend to higher temperature stable state;If less than the critical value, the turn to low temperature condition.memoria ram ddr3 4gb 1333mhz
Through the use of thermal probe to control the temperature of the hot end, data can be written to and stored in memory, read the data by measuring a probe temperature insulation.
In the future, nano thermal mechanical memory as a logical device to use, it also possesses the advantages of can under the environment of high temperature operation.The researchers then will achieve their memory design through experiments."We are currently making a near-field nano thermal mechanical memory working prototype."Engda says.
