Abstract: Provided are a light source module and a backlight unit (BLU) including the same. The light source module includes a substrate including a base plate extending in a first direction and a pair of dam structures stacked on opposing sides of the base plate along a second direction, orthogonal to the first direction, and extending along the base plate in the first direction, wherein the pair of dam structures are spaced apart from each other along a third direction, orthogonal to the first and second directions. A plurality of light-emitting devices are mounted on the substrate between the pair of dam structures and spaced apart from one another in the first direction. An encapsulation layer covers at least one side surface and a top surface of each of the plurality of light-emitting devices. A height of the pair of dam structures is greater than a height of the encapsulation layer.

Abstract: Memory devices are provided. A memory device includes a voltage generation circuit that includes an offset compensator configured to receive a reference voltage and an offset code and to link the offset code to the reference voltage. The voltage generation circuit includes a comparator configured to compare the reference voltage linked to the offset code with a bit line pre-charge voltage and to output driving control signals. The voltage generation circuit includes a driver configured to output the bit line pre-charge voltage at a target level of the reference voltage in response to the driving control signals. The voltage generation circuit includes a background calibration circuit configured to generate the offset code for performing control so that a target short current flows through an output node of the driver from which the bit line pre-charge voltage is output. Related methods of generating a bit line pre-charge voltage are also provided.
