  • Publication number: 20240389299
    Abstract: A memory cell includes a write access transistor, a storage transistor, and a read access transistor. A gate of the write access transistor is connected to a write word line, a source of the write access transistor is connected to a write bit line, and a drain of the write access transistor is connected to a gate of the storage transistor. A source of the storage transistor is connected to a source line and a drain of the storage transistor is connected to a source of the read access transistor. A gate of the read access transistor is connected to a read bit line and a drain of the read access transistor is connected to read bit line. The memory cell further includes a capacitive element having a first connection to the gate of the storage transistor and a second connection to a reference voltage source.

  • Publication number: 20240381796
    Abstract: A resistive memory device includes a bottom electrode, a switching layer including a first horizontal portion, a second horizontal portion over an upper surface of the bottom electrode, and a first vertical portion over a side surface of the bottom electrode, a top electrode including a first horizontal portion over the first horizontal portion of the switching layer, a second horizontal portion over the second horizontal portion of the switching layer, and a first vertical portion over the first vertical portion of the switching layer, and a conductive via contacting the first horizontal portion, the second horizontal portion and the first vertical portion of the top electrode. By providing a switching layer and a top electrode which conform to a non-planar profile of the bottom electrode, charge crowding and a localized increase in electric field may facilitate resistance-state switching and provide a reduced operating voltage.

  • Publication number: 20240348921
    Abstract: An image processing device is provided. The device includes an electronic image stabilization (EIS) module and an image signal processing (ISP) module. The EIS module is configured to determine EIS information for a video frame based on motion information that corresponds to the video frame, wherein the EIS information is associated with the target region and the margin region of the video frame. The ISP module is configured to generate a processed video frame based on the EIS information by performing an ISP process only on the target region of the video frame and skipping the ISP process on the margin region of the video frame. The EIS module is further configured to generate a stabilized image based on the EIS information and the processed video frame.
