A light emitting device having a vertical structure and a method for manufacturing the same, which are capable of damping impact generated during a substrate separation process and achieving an improvement in mass productivity, are disclosed. The light emitting device includes a semiconductor layer having a multilayer structure, a first electrode arranged at one surface of the semiconductor layer, a metal support arranged on the first electrode, and an impact damping layer arranged between the first electrode and the metal support, and made of a metal having a ductility higher than a ductility of a metal for the metal support.
摘要:
A system code is stored in a first nonvolatile memory. The first nonvolatile memory and a second nonvolatile memory are heated during assembly of an electronic device including the first nonvolatile memory and a second nonvolatile memory. The heating is to a temperature sufficient to change a state of at least some memory cells in the second nonvolatile memory device. After the heating, the system code stored in the first nonvolatile memory is copied into the second nonvolatile memory. The first nonvolatile memory may he less vulnerable to temperature-related data alteration than the second nonvolatile memory. For example, the first nonvolatile memory may include a NAND flash memory and the second nonvolatile memory may include a variable resistance memory.

An LED having vertical topology and a method of making the same is capable of improving a luminous efficiency and reliability, and is also capable of achieving mass productivity. The method includes forming a semiconductor layer on a substrate; forming a first electrode on the semiconductor layer; forming a supporting layer on the first electrode; generating an acoustic stress wave at the interface between the substrate and semiconductor layer, thereby separating the substrate from the semiconductor layer; and forming a second electrode on the semiconductor layer exposed by the separation of the substrate.
摘要:
A storage device performs a program operation to store program data in a selected memory block of a flash memory. The storage device allocates a reserved area of the flash memory as a free block upon detecting that a program failure has occurred in the program operation, reads the program data from a cache latch in a page buffer of the flash memory, copies valid data stored in the selected memory block to a first area of the free block, and reprograms the program data read from the cache latch to a second area of the free block.

Provided are systems and methods to communicate data transfer of data between a disk device and an external storage device. A host can generate a control command to communicate with an external storage device, and a disk device to receive the control command from a host to identify and communicate with an external storage device when connected to the external storage device and to configure the external storage device by assigning an ID code to each storage area of the external storage device.
