Abstract: The present application discloses a semi-floating gate device. A floating gate structure covers a selected area of a first well region and is used to form a conductive channel. The floating gate structure further covers a surface of a lightly doped drain region, and a floating gate material layer and the lightly doped drain region contact at a dielectric layer window to form a PN structure. A source region is self-aligned with a first side surface of the floating gate structure. A first control gate is superposed on a top of the floating gate structure. A second control gate is disposed on a surface of the lightly doped drain region between the drain region and a second side surface of the floating gate structure. The first control gate and the second control gate are isolated by an inter-gate dielectric layer.

Abstract: Parallel mark processing is disclosed including traversing first objects in a virtual machine heap based on correspondences between memory blocks in the virtual machine heap and N marking threads, pushing a first pointer of a first object into a private stack of a marking thread corresponding to a memory block, the first object being located in the memory block, performing first mark processing of the first object based on a push-in condition of the first pointer, and after traversal of the first objects has been completed, launching the N marking threads to cause the N marking threads to synchronously perform mark processing used in garbage collection based on push-in conditions of first pointers in respective private stacks of the first pointers.

Abstract: An image forming apparatus includes an image scanning device, which comprises: a document tray to load an original document to be scanned; a discharge tray to load the original document after being scanned; and a frame which the document tray and the discharge tray are mounted on. A conveyance path is formed inside the frame to connect the document tray and the discharge tray. The frame contains a conveying structure to convey the original document along the conveyance path; a transparent support member located below the conveyance path to support the original document; a scanning member located below the transparent support member, the scanning member having a scanning position in which the scanning member scans the original document when being located on the transparent support member; and a pressing member disposed above the transparent support member and facing the scanning member for pressing the original document onto the transparent support member.

Abstract: The present disclosure provides a scanning device, an image-forming apparatus, and a scanning method. In one aspect, the scanning device provided by the present disclosure includes a first sensor, a second sensor, a first channel corresponding to the first sensor, a second channel corresponding to the second sensor, and a selector. The first sensor is configured to collect first image data of a to-be-scanned document. The second sensor is configured to collect second image data of the to-be-scanned document. The selector is configured to acquire image data alternately from the first channel and the second channel to acquire a pixel of the first image data from the first channel and a pixel of the second image data from the second channel by using a pixel-by-pixel acquisition mode for each of the first and second channels in one acquisition cycle.
