摘要:
A hierarchical DRAM sensing apparatus and method which employs local bit line pairs and global bit lines. A word line selects the cells in a cluster of sense amplifiers, each of the amplifiers being associated with a pair of bit lines. One of the local bit lines is selected for coupling to global bit lines and a global sense amplifier. Clusters are located in a plurality of subarrays forming a bank with the global bit lines extending from each of the banks to the global sense amplifier.

A NOR architecture for selecting a word line driver in a DRAM is disclosed. Complements of separately decoded addresses in the low, mid and high ranges are used to select a final word line driver. The output of the word line driver is at a potential negative with respect to ground for a deselected word line and a positive potential more positive than the power supply potential for a selected word line.

A multistage read can dynamically change wordline capacitance as a function of threshold voltage of a memory cell being read. The multistage read can reduce current spikes and reduce the heating up of a memory cell during a read. A memory device includes a global wordline driver to connect a wordline of a selected memory cell to the sensing circuit, and a local wordline driver local to the memory cell. After the wordline is charged to a read voltage, control logic can selectively enable and disable a portion or all of the global wordline driver and the local wordline driver in conjunction with applying different discrete voltage levels to the bitline to perform a multistage read.

Methods and systems that provide for cross-linking from composite images that include receiving, over a computer network, a source image and then associating a first identifier tag with a first object in the source image. A composite image is generated from the source image, wherein the composite image includes a cropped image of the first object. Then a first user is notified that the first identifier tag is associated with the first object in the cropped image and also includes a copy of the composite image. Additionally, the user can select the first object in the composite image and be linked to the source image that contains the selected first object where the first object is highlighted.

A fiber Bragg grating cross-wire sensor may be used to independently determine strain and temperature variation. An example fiber Bragg grating cross-wire sensor comprises a first fiber Bragg grating (FBG) that reflects a first percentage, R1, of light of a first wavelength, λ1, and a second FBG that reflects a second percentage, R2, of light of a second wavelength, λ2. The second FBG is positioned orthogonal to the first FBG, and λ1 is substantially equal to λ2, but R1 is different from R2. As the FBG cross-wire sensor experiences a strain and/or a temperature variation, the wavelengths of light reflected by the first FBG and the second FBG will shift from the first and second wavelength, λ1 and λ2, to first and second shifted wavelengths, λA and λT, respectively. Based on R1, R2, λ1, λA, and λT, the strain and/or the temperature variation may be independently determined.

摘要:
In accordance with one embodiment, a serial sensing scheme may be utilized to sense the information stored on a multilevel cell. The more significant bit of the information in the cell may sense initially. The more significant bit information may be used to determine which of at least two reference levels to utilize to determine a less significant bit of the cell.
