| 20090168589 | Thermal code transmission circuit and semiconductor memory device using the same - Disclosed are a thermal code transmission circuit and a semiconductor memory device using the same. The thermal code transmission circuit includes a select signal generator which generates a select signal in response to a first enable signal, a level signal generator which receives the first enable signal to generate a level signal, an update signal generator which receives the level signal and a first update signal to generate a second update signal, a latch unit which receives a thermal code in response to the second update signal and outputs the thermal code as an output thermal code, and a thermal code output unit which selectively outputs the output thermal code in response to the select signal. | 07-02-2009 |
| 20100232251 | METHOD AND SYSTEM FOR CODING AND READ OUT OF INFORMATION IN A MICROSCOPIC CLUSTER COMPRISING COUPLED FUNCTIONAL ISLANDS - A method and a system for coding and reading out information in a microscopic cluster formed with coupled functional islands includes: generating the cluster by forming a regular microscopic pattern for locating the functional islands; making use of a physical or chemical property of each individual island and making use of the coupling between the functional islands; assigning different information to different energy levels of the cluster; effecting a change of the physical or chemical property of at least one functional island in order to change the energy level of the cluster to the energy level equivalent to the information content to be coded; and reading out the information. These measures allow forming a cluster having distinct energy levels, each being assigned to a distinct information content. These systems pave the way for future devices based on clusters of coupled islands and, armed with the complete knowledge of the energy states, the door is opened for use of these finite multistate clustered structures in future spintronic devices, for example for data storage, memory applications or to perform logic operations. | 09-16-2010 |

| 20110026296 | Nonvolatile Optical Memory Element, Memory Device, and Reading Method Thereof - A nonvolatile optical memory element in which a ferromagnetic body is provided on a semiconductor causes such a problem that in a case where magnetization of the ferromagnetic body is read by light, magneto-optical response becomes very small when the ferromagnetic body is small in volume. The present invention provides a memory element, a memory device, and a data reading method, each of which is applicable to data reading from a nonvolatile optical memory element. In a nonvolatile optical memory element having a structure in which a ferromagnetic body is provided on a semiconductor that is connected to an optical waveguide, electrons are injected into the semiconductor via the ferromagnetic body so that the electrons that are spin-polarized according to a magnetization direction of the ferromagnetic body are injected into the semiconductor, thereby enlarging a region in which a photomagnetic effect occurs effectively. By applying an electric pulse and an optical pulse to the nonvolatile optical memory element, it is possible to effectively read recorded data according to a magnetization direction of the ferromagnetic body. | 02-03-2011 |
