    Abstract: A device for imaging comprising an image sensor is disclosed. The image sensor includes rows and columns of pixels. The image sensor further includes a first control structure for controlling transfer of accumulated electric charges from photo-active regions to transmission regions in pixels. The image sensor further includes a second control structure for controlling transfer of accumulated charge in the transmission region of each row to the adjacent row below. The first and second control structures control the image sensor to alternately transfer accumulated charges in photo-active regions to the transmission regions and transfer charges to the adjacent row below. The control structure includes a plurality of row structures which are arranged to select whether the charge in the photo-active regions of respective rows are added to the transmission region. Each row of pixels is controlled by one of the row structures of the first control structure.

    Abstract: According to an aspect, a method of forming a memory structure for a 3D NAND flash memory includes forming a layer stack over a substrate, forming first recessed areas in a sidewall surrounding a memory hole in the layer stack by laterally etching back gate layers of the layer stack from the memory hole, and forming a lateral memory stack in each first recessed areas, by depositing a blocking oxide and, subsequently, a charge trap material. The method also includes forming second recessed areas in the sidewall by laterally etching back the inter-gate spacer layers from the memory hole and forming dummy layers in the second recessed areas. The method also includes lining the sidewall of the memory hole with a liner layer, subjecting the dummy layers to a thermal treatment process adapted to convert each dummy layer into an air gap structure, and forming a tunneling oxide layer in the memory hole, along the liner layer, and a channel layer along the tunneling oxide layer.

    Abstract: This disclosed technology relates to a programmable NAND flash memory and a method for operating the NAND flash memory. The method comprises applying a first voltage to the first gate and a pass voltage to one or more word lines to allow charge to inject into the channel layer and form charge packets. Each charge packet can be arranged next to one of the second gates. The method further comprises applying a programming voltage to the word lines to move the charge packets from the channel layer into the memory cells associated with the second gates next to which they are arranged.
