Patent number: 8659941Abstract: A nonvolatile memory includes a memory cell including a first transistor and a second transistor. The first transistor includes a first channel, a first gate electrode, a first source electrode, and a first drain electrode. The second transistor includes a second channel made of oxide semiconductor material, a second gate electrode, a second source electrode, and a second drain electrode. One of the second source electrode and the second drain electrode is electrically connected to the first gate electrode. Data writing in the memory cell is done by raising the potential of a node between one of the second source electrode and the second drain electrode and the first gate electrode. Data erasure in the memory cell is done by irradiating the second channel with ultraviolet light and lowering the potential of the node.Type: GrantFiled: November 22, 2010Date of Patent: February 25, 2014Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Koichiro Kamata, Yusuke Sekine -
Patent number: 8611129Abstract: An operation method of a semiconductor device, includes providing one or more memory elements each including a first semiconductor layer of a first conductivity type, second and third semiconductor layers of a second conductivity type, which are disposed to be separated from each other in the first semiconductor layer, a first electrode electrically connected to the second semiconductor layer, and a second electrode electrically connected to the third semiconductor layer, and performing operation of writing information on a memory element to be driven of the one or more memory elements. The operation of writing is performed by forming a filament in a region between the second and third semiconductor layers, which is a conductive path electrically linking these semiconductor layers, through application of a voltage equal to or higher than a predetermined threshold between the first electrode and the second electrode.Type: GrantFiled: January 30, 2012Date of Patent: December 17, 2013Assignee: Sony CorporationInventors: Shigeru Kanematsu, Yuki Yanagisawa, Matsuo Iwasaki

Patent number: 8551844Abstract: Some embodiments include methods in which first insulative material is formed across a memory region and a peripheral region of a substrate. An etch stop structure is formed to have a higher portion over the memory region than over the peripheral region. A second insulative material is formed to protect the lower portion of the etch stop structure, and the higher portion is removed. Subsequently, at least some of the first and second insulative materials are removed. Some embodiments include semiconductor constructions having a first region with first features, and a second region with second features. The first features are closer spaced than the second features. A first insulative material is over the second region and an insulative structure is over the first insulative material. The structure has a stem joined to a bench. The bench has an upper surface, and the stem extends to above the upper surface.Type: GrantFiled: May 25, 2012Date of Patent: October 8, 2013Assignee: Micron Technology, Inc.Inventor: Zengtao T. Liu
