Abstract: Provided are a memory device and a memory system performing request-based refresh, and an operating method of the memory device. The operating method includes: determining a weak row by counting an activated number of at least one row; requesting for refresh on the weak row based on a result of the determining; and performing target refresh on the weak row upon receiving a refresh command according to the requesting.

Abstract: Provided are a quantum dot glass cell and a light-emitting device package including the quantum dot glass cell. The quantum dot glass cell may include a quantum dot powder in which quantum dots, inorganic homogenizing particles, and a binder are mixed, a dispersion matrix in which the quantum dot powder is dispersed, and a glass sealing structure surrounding the dispersion matrix. The quantum dot glass cell and the light-emitting device package including the quantum dot glass cell may have improved light emission characteristics and improved reliability.

Abstract: Provided are a light source package and a display device including the light source package. The light source package includes a substrate; a light-emitting device mounted on the substrate; a red phosphor layer formed adjacent to a surface of the light-emitting device; and an encapsulation layer for encapsulating the light-emitting device and the red phosphor layer, wherein a phosphor of the red phosphor layer is a fluoride-based red phosphor or a sulfide-based red phosphor. The light source package and the display device including the light source package display excellent color reproduction, without discoloration due to moisture after a long period of time.
