    Abstract: A method for detecting a defect on a substrate, including receiving a first image, generating a second image, by converting the first image to grayscale levels, calculating a first gray level value, having a maximum number of pixels in the second image, and second and third gray level values, having a number of pixels in the second image equal to a predetermined fraction of the first gray level value, from a histogram of the number of pixels respective to the grayscale levels of the second image, converting the second image into a third image having pixels at a level lower than that of the first gray level value and a fourth image having pixels at a level equal to or higher than the first gray level value, generating fifth and sixth images by detecting edges by applying a Canny algorithm to the third and fourth images, respectively.

    Abstract: Methods of operating nonvolatile memory devices include counting a number of consecutive read operations performed on a first memory region within the nonvolatile memory device, and executing a page reclaim operation on the first memory region in response to detecting that a count in the number of consecutive read operations meets or exceeds a threshold count. A page reclaim operation may include checking an error bit level within a page of data stored in a multi-level cell block within the memory device. The page reclaim operation may further include moving page data from the multi-level cell block to a single-level cell block in the memory device and error correcting the page data during the moving.

    Abstract translation: 操作非易失性存储器件的方法包括对在非易失性存储器件内的第一存储器区域执行的连续读取操作的数量进行计数，以及响应于检测到连续读取数量的计数，对第一存储器区域执行页面回收操作 操作满足或超过阈值计数。 页面回收操作可以包括检查存储在存储器设备内的多级单元块中的数据页内的错误位级别。 页面回收操作可以进一步包括将页面数据从多级单元块移动到存储器件中的单级单元块，并且在移动期间纠错页面数据。

    Abstract: An electronic device according to an embodiment of the disclosure includes a communication circuit, a memory, and a processor configured to be operatively connected to the communication circuit and the memory. The processor may be configured to control the communication circuit to perform wireless communication through a first access point, to search for another access point while performing communication through the first access point, and attempt to connect to a candidate access point selected based on a block list stored in the memory, and to store, when a designated event occurs while attempting to connect to the candidate access point, a recovery condition configured according to a type of the designated event together with identification information of the candidate access point in the block list.

    Abstract: An electronic device comprises: at least one communication circuit configured to provide communication with a first external electronic device or a second external electronic device; at least one processor operatively connected to the at least one communication circuit; and a memory including device registration request information and operatively connected to the at least one processor, wherein the memory may store instructions configured to cause, when executed, at least one processor to: transmit, to the first external electronic device, a device registration request including at least device registration request information for registering the electronic device to the second external electronic device when a first communication is connected with the first external electronic device through the at least one communication circuit; receive a response to the device registration request from the first external electronic device; receive, from the second external electronic device, device registration update information that is updated on the basis of the registration request of the electronic device, based on the response, when a second communication is connected with the second external electronic device through the at least one communication circuit; and store the received device registration update information in the memory.
