    Abstract: Various embodiments of the present invention relate to an access control method for a smart card and an electronic device using the same, the method comprising the steps in which: a processor refreshes the smart card to update identification information when the electronic device is located in a predetermined region; the processor stores, in a memory, information before the identification information is updated; the processor stores the updated identification information in smart card information of the smart card; the processor checks whether identification information before the update is stored in the memory when the updated identification information is included in blacklist information of the memory; the processor determines whether the identification information before the update is included in the blacklist information; and the processor allows an access to the smart card, when the identification information before the update is not included in the blacklist information, such that a user normally buying and using an electronic device at a specific region could not have a limitation related to regional locking, caused by refreshing of identification information of the smart card, which can occur while visiting a country on a blacklist. Other various embodiments are possible.

    Abstract: A comparison circuit that includes an input sampling capacitor and an image sensor including the same are provided. The comparison circuit includes an amplifier configured to receive a pixel signal and a ramp signal to perform a correlated double sampling operation, a first pixel capacitor connected to the amplifier through a first floating node and configured to transmit the pixel signal, a first ramp capacitor connected to the amplifier through a second floating node and configured to transmit the ramp signal, a second pixel capacitor connected in parallel to the first pixel capacitor, and a second ramp capacitor connected in parallel to the first ramp capacitor, wherein the second pixel capacitor is formed between the first floating node and first peripheral routing lines, and the second ramp capacitor is formed between the second floating node and second peripheral routing lines.

    Abstract: Provided are a memory system and an operating method thereof. The operating method reads an observation memory cell at least one time with different read voltages to configure a first read data symbol, reads a plurality of interference memory cells adjacent to the observation memory cell at least one time with different read voltages to configure second read data symbols, and determines a logical value of the observation memory cell based on the first read data symbol and the second read data symbols.
