Abstract:
A semiconductor memory device includes a plurality of phase change memory cells connected to the same bitline and different respective word lines. A read operation is performed on one of the memory cells by selecting the bitline and a corresponding wordline. While the read operation is performed, leakage current produced by non-selected memory cells is detected by a leakage detecting circuit and compensated by a leakage current supply circuit.
Abstract:
A target detecting system and method for detecting a target from an input image is provided. According to the target detecting system and method, when a target is detected from an input image and there are moving areas in the input image, camera movement parameters are obtained, image frames are transformed, and movement candidate areas are extracted from the image frame and the previous input image frame. In addition, image feature information is extracted from the input image, and based on the movement candidate areas and the image feature information a shape of the target is extracted. Therefore, the target can be exactly and rapidly extracted and tracked.
