  • Patent number: 11586387
    Abstract: Provided herein may be a memory system. The memory system may include a memory device including a memory block and a peripheral circuit, and a memory controller configured to transmit a program command based on a single-level cell scheme to the memory device so as to increase threshold voltages of the selection transistors included in the memory block after an erase operation has been performed on the memory block, and transmit, to the memory device, a read command to perform a check operation, wherein the read command indicates a first read voltage and a second read voltage higher than the first read voltage, and the check operation includes a check of whether the threshold voltages fall within a range between the first and second read voltages, or a check of whether the threshold voltages are lower than the first read voltage or higher than the second read voltage.

  • Patent number: 11061615
    Abstract: A memory system, a memory controller and an operating method thereof. The memory system includes a memory device including a plurality of memory blocks; and a memory controller configured to control the memory device. During an idle time, the memory controller searches for a target read bias for a first word line among a plurality of word lines in a first memory block of the memory device, and generates a history including the target read bias.

  • Patent number: 8120691
    Abstract: Provided are an image capturing apparatus and method for use in a mobile terminal. The image capturing method includes when an image capturing menu is selected during a preview operation, pausing the preview operation; releasing an image sub-processing of the preview operation; and resuming the preview operation and capturing the image. Accordingly, the mobile terminal can minimize the difference between the preview operation stop time and the capture time, which may be generated by the data processing time increased during capturing the image at high pixel resolution. Therefore, the mobile terminal can provide the captured image naturally.

  • Publication number: 20050233697
    Abstract: Disclosed is a method for creating vCards on a mobile terminal using a user's own design and for easily exchanging the vCards between mobile terminals and other electronic devices. A vCard displayed on a mobile terminal is stored as image data in a JPEG file. Since the mobile terminal sends an image file generated by the combination of the user information in the vCard with corresponding image data in a predetermined format, it has an improved vCard compatibility with other devices. Moreover, users can create graphics intensive vCards that satisfy their demand for distinctiveness. A recipient's mobile terminal that receives a graphics intensive vCard can store the same vCard as displayed in a JPEG image file or (to conserve valuable resources) store the user information extracted from the vCard, for example, by updating an existing vCard database. Accordingly, vCard compatibility is improved between mobile terminals and other devices (for example, desktop and notebook PCs).

  • Publication number: 20040058718
    Abstract: A method for giving notice of incoming call through vibration of a mobile communication terminal, and more particularly a method for giving notice of an incoming call through various vibration patterns. The method configures various vibration patterns according to a user's selection, sets the vibration patterns in a basic or particular incoming call notification mode of the mobile communication terminal, and generates vibration based on a set vibration pattern in the basic incoming call notification mode or generates vibration based on a particular vibration pattern mapped to a particular caller telephone number set in the particular incoming call notification mode when the incoming call is received.
