A polymerizable optical composition includes first and second monomers. The weight ratio of the first monomer to the second monomer is from 1:9 to 9:1. The second monomer contains at least one acryl functional group. The first monomer is represented by a formula [A]: wherein R1 is selected from one of O and S atoms; R2 is a bivalent functional group of (C2H4O)n, where n is an integer from 1 to 10; and R3 is selected from one of H and CH3.

A method of programming memory cells for a rewritable non-volatile memory module is provided. The method includes: receiving a command which indicates performing an update operation to a logical page; and identifying valid logical access addresses and invalid logical access addresses in the logical page according to the command. The method also includes: selecting a physical page; setting flags corresponding to the valid logical access addresses in a valid state, setting flags corresponding to the invalid logical access in an invalid state; programming the flags and data belonging to the valid logical access addresses to the selected physical page based on the update operation; and mapping the selected physical page to the logical page. Accordingly, the method can effectively increase the speed of programming the memory cells.

A media-broadcasting device having USB slots is described. The media-broadcasting device connects to a USB-based memory device through the USB slot and has a main controller connected to the memory device through the USB slot for access to digital data stored in the memory device, an interior memory buffer connected to the main controller for temporarily storing the digital data under the command of the main controller, and an MP3 module connected to the main controller for retrieving and processing the digital data through the main controller.

摘要:
A semiconductor package is disclosed, such as QFN, SON. The semiconductor package includes a die, a package body for protection of a die, and a plurality of leads. A metal pad formed by some partial downside surface of each lead is located on a downside surface of the package body with coplanarity. Each lead has a cutting surface exposed on a corresponding lateral surface of the package body. The cutting surface has an interval with the plane of forming the metal pads by means of selectively self-etching the leads or stamping to bend the leads in order to avoid forming a cutting sharp edge in the brim of the metal pad after cutting.
