Embodiment
The memory storage that present embodiment provides, utilize the spread geometry of a plurality of former molecular atomic unit group Atoms, data bit (bit) when representing the data storage, wherein the shape of atomic unit group can change by the mode that atom-probe moves atom, so that the atomic unit group can changed between two shapes under the atom-probe effect, a shape can represent that 0, one shape of data bit can represent data bit 1, therefore, an atomic unit group can be used to represent data bit.For ease of the understanding to embodiment of the invention technical scheme, the below will describe atom-probe and atom storage medium.
Along with the research of people to material technology and atom technology, the existing technology that atom is operated, namely the atom-probe technology has been applied in the application technology that some atoms control.
Wherein, the atom-probe technology is that material surface is carried out a kind of technology that atom is surveyed and operated, has atom level high-space resolution ability, can be used for processing ultra-fine grain structure, it can realize that mainly Measurement atom imaging and operation atom are to ad-hoc location, wherein the Measurement atom imaging just can be identified the spread geometry of atom, and the operation atom just can be realized the movement of atom to ad-hoc location.At present, the atom-probe technology has been widely applied in the technology such as STM, wherein, utilizes atom-probe can identify the shape on sample surface among the STM, and can carry out position movement to atom, is described as follows.
When STM carries out the atomic arrangement shape recognition, during the card distance＜1nm on atom-probe and sample surface, scan by the probe tip effects on surface atom in the piezoceramic material control atom-probe, thereby can analyze the atomic arrangement situation, so just can identify the atomic arrangement shape.And utilize STM to carry out atom site when moving, the acting force that can utilize atom-probe and sample surface to exist, regulate position and the bias voltage of needle point, by changing the size and Orientation of this acting force, just can when moving up, probe mention the atom on sample surface, again it is moved to suitable position and put down, perhaps, also can pull atom and pass by the surface to the desired position.The specific works process of STM Atom probe no longer describes in detail at this, in detail can be referring to the course of work of existing STM, present embodiment adopts atom-probe that the atomic arrangement shape is identified, and atom site moved has the course of work identical with STM.
In the prior art, developed the stable material of atom, for example Wisconsin, USA university develops the silicon memory material of atom level, after the silicon materials surface allows gold element distil, can form the accurate atomic orbital that is used for atomic arrangement.At present, also utilize atom-probe, silicon atom is extracted at the interval out from the silicon atom of marshalling, the data bit 0 during with the storage of expression data, and remaining silicon atom is representative data position 1 then.But this method of utilizing atom to have or not to represent data bit very easily causes data storage errors because of the atom dislocation.For this reason, the embodiment of the invention provides a kind of technical scheme of utilizing the atomic arrangement shape to represent data bit, can when utilizing atom as the data storage, improve the safety and reliability of data storage.
The structural representation of the memory storage that Figure 1A provides for the embodiment of the invention one; Figure 1B is the enlarged diagram that 8 continuous atomic unit groups are arranged among the annular region A among Figure 1A.Shown in Figure 1A and Figure 1B, the present embodiment memory storage can be used for storing data, comprises storage medium 10, is arranged with a plurality of atomic unit groups 11 by default rule on this storage medium 10, and each atomic unit group 11 forms by a plurality of atoms; The spread geometry of atomic unit group 11 Atoms can change, and has first order shape and second order shape, and wherein, the first order shape is used for expression data bit 1, and the second order shape is used for expression data bit 0.In the present embodiment, storage medium 10 is disc-shape, and atomic unit group 11 is evenly arranged on the storage medium of this disc-shape, in the concentric a plurality of annular regions of disk.Wherein, Figure 1A only illustrates an annular region A, and wherein said annular region A is a zone of arranging the atomic unit group; Figure 1B only illustrates the arrangement synoptic diagram of 8 atomic unit groups in the A annular region.
In the present embodiment, the number of each atomic unit group 11 Atom on the storage medium can be for more than 2 or 2, preferably, as shown in Figure 1B, the number of each atomic unit group 11 Atom is set as 6 in the present embodiment, like this, the first order shape that the arrangement of atomic unit group 11 Atoms forms just can be the rectangular shape of 6 atomic arrangement formation, the second order shape just can for 6 atomic arrangement form triangular shaped, the rectangular shape A1 that 6 atoms as shown in Figure 1B form, and 6 triangular shaped A2 that atom forms.Like this, above-mentioned atom-probe just can just can change the shape of atomic unit group 11 by in mobile 6 atoms, can be converted to rectangle by triangle; Simultaneously, above-mentioned atom-probe can be by detecting the spread geometry of 6 atoms in the atomic unit group, the data bit of determining the current expression of atomic unit group is 0 or 1, wherein, atomic unit group Atom spread geometry represents when being rectangle that current atomic unit group represents data bit 1, and atomic unit group Atom spread geometry represents when being triangle that current atomic unit group represents that data bit is 0.So, just can identify the data bit of atomic unit group representative by the shape of identification atomic unit group, thus can be by the read operation of identification atomic unit group Atom spread geometry realization to data; By the position of mobile atomic unit group Atom, just can change the shape of atomic unit group, thereby can change by the shape of identification atomic unit group and to the shape of atomic unit group, just can realize the write operation of data.Its specific implementation describes in the embodiment of the method in the back.
In the present embodiment, represent the data bit (0/1) of storing by atom first order shape and second order shape.Only need to an atom in the atomic unit group be moved, just can change the spread geometry of atomic unit group, realize the conversion of data bit 1 and 0.
