Abstract: An image sensor includes a substrate including a plurality of pixel regions and having a trench between the pixel regions, a photoelectric conversion part in the substrate of each of the pixel regions, and a device isolation pattern in the trench. The device isolation pattern defines an air gap. The device isolation pattern has an intermediate portion and an upper portion narrower than the intermediate portion.

Abstract: An image sensor includes photoelectric conversion devices provided in a substrate comprising first and second surfaces, first and second photoelectric conversion elements in the substrate, first and second separation structures in the substrate, first and second grid structures on the first and second separation structures. The second photoelectric conversion element is disposed between the first separation structure and the second separation structure. The first and second grid structure are vertically overlapping with the first and second separation structure. The first grid structure comprises an air gap and N plurality of layers on an external side surface of the air gap. Each of the N plurality of layers extends in a first direction. The second grid structures comprises M plurality of layers on an external side surface of the second grid structure and extends in the first direction.

Abstract: A method of operating a memory controller is provided. The method includes: receiving a write request from a host; determining whether to inactivate a throttling operation based on whether the write request corresponds to a throttling disable word line and whether a memory block corresponding to the write request needs to be erased; and performing a write operation corresponding to the write request based on the determining.

Abstract: An image sensor includes a substrate including a pixel array region and an optical black region surrounding the pixel array region, a micro lens over the pixel array region, a dummy lens over the optical black region, and a blocking bar over the optical black region. A length of the blocking bar is greater than a length of the micro lens and a length of the dummy lens. A top surface of the blocking bar is curved.
