An electronic apparatus includes: a memory, a communication interface comprising communication circuitry configured to communicate with a first external device and a second external device, a projection part configured to output an image to a projection surface, and a processor configured to: receive first data including a first image from the first external device, receive second data including a second image from the second external device, acquire first position information of the first external device and second position information of the second external device, acquire a projection image including the first image and the second image based on the first position information and the second position information, and control the projection part to output the projection image.

Electronic apparatus and controlling method thereof

An electronic apparatus includes a projector, an input/output interface, a memory, and a processor that controls the electronic apparatus by executing at least one instruction stored in the memory. The processor obtains screen information of a screen device connected to the electronic apparatus, controls the input/output interface to transmit first operation information corresponding to an unrolling of the screen device in response to receiving a user command to project an image, and controls the projector to project a first image to at least a partial region of a region in which a screen of the screen device is exposed based on the screen information while the screen of the screen device is being unrolled, based on the first operation information.

Electronic apparatus and control method thereof

Methods of programming or erasing a nonvolatile memory device having a charge storage layer including performing at least one unit programming or erasing loop, each unit programming or erasing loop including applying a programming pulse, an erasing pulse, a time delay, a soft erase pulse, soft programming pulse and/or a verifying pulse as a positive or negative voltage to a portion (for example, a word line or a substrate) of the nonvolatile memory device.

Program and erase methods for nonvolatile memory

Example embodiments are directed to methods, memory devices, and systems for programming a nonvolatile memory device having a charge storage layer including performing at least one unit programming loop, each unit programming loop including, applying a programming pulse to at least two pages, applying a time delay to the at least two pages, and applying a verifying pulse to the at least two pages.

Programming methods for nonvolatile memory

Methods of programming or erasing a nonvolatile memory device having a charge storage layer including performing at least one unit programming or erasing loop, each unit programming or erasing loop including applying at least one programming pulse, at least one erasing pulse, at least one time delay, at least one soft erase pulse, at least one soft programming pulse and/or at least one verifying pulse as a positive or negative voltage to a portion (for example, a word line or a substrate) of the nonvolatile memory device.
