Crossbar arrays are the most promising application of a resistive random access memory (RRAM) device for achieving high density memory. However, cross-talk interference in the crossbar array limits the increase in the integration density. In this paper, the combination of two anti-parallel connected diodes and a bipolar RRAM cell is proposed to suppress the sneak current in a crossbar array with anti-parallel connected diodes as the selector for the bipolar RRAM. By using the anti-parallel connected diodes as a selector, the sneak current can be effectively suppressed and the high density crossbar array of more than 1 Mb can be realized as estimated by the 1/2V read voltage scheme. These results indicate that anti-parallel connected diodes can be used as a bipolar selector and have great potential for high density bipolar RRAM crossbar array applications.

Protein domains of approximately 120 amino acids that form two perpendicular anti-parallel beta sheets connected by a loop of variable length and a C-terminal amphipathic helix. PH domains occur in many INTRACELLULAR SIGNALING PROTEINS and CYTOSKELETAL PROTEINS where they bind PHOSPHATIDYLINOSITOLS within the CELL MEMBRANE and INTRACELLULAR MEMBRANES, as well as proteins that include the Betagamma-subunits of HETEROTRIMERIC GTP-BINDING PROTEINS, and PROTEIN KINASE C. These interactions allow the targeting of proteins to different cellular compartments and SIGNAL TRANSDUCTION PATHWAYS.
An amino acid sequence of about 50 residues long that is composed of X n-long repeats which form a four-stranded anti-parallel BETA-SHEET as a structural component, or blade, of a beta-propeller.
A subfamily of HELIX-TURN-HELIX DNA-binding proteins that contain a variable length loop adjacent to the HTH motif. The loop connects two anti-parallel strands and forms a wing when bound to DNA.
INTERNEURONS of the vertebrate RETINA containing two processes. They receive inputs from the RETINAL PHOTORECEPTOR CELLS and send outputs to the RETINAL GANGLION CELLS. The bipolar cells also make lateral connections in the retina with the RETINAL HORIZONTAL CELLS and with the AMACRINE CELLS.
Projection of near-IR light (INFRARED RAYS), in the 700-1000 nm region, across an object in parallel beams to an array of sensitive photodetectors. This is repeated at various angles and a mathematical reconstruction provides three dimensional MEDICAL IMAGING of tissues. Based on the relative transparency of tissues to this spectra, it has been used to monitor local oxygenation, brain and joints.
Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. Over half of Bipolar cases develops before the age of 25. Bipolar ...
A diagnostic test is any kind of medical test performed to aid in the diagnosis or detection of disease. For example: to diagnose diseases to measure the progress or recovery from disease to confirm that a person is free from disease Clin...
