July 31, 2003, Taipei】TwinMOS, a leading memory module manufacturer, recently announced the TwiSTER, a series of new-generation WLCSP-based DRAM modules. The company named the new product line – TwiSTER after the core concepts incorporated into the technology with “S” standing for “speed” and “TER” standing for “terrific” to approach over-clocking power users、gaming enthusiasts and business customers with its high performance and speedy yet steady retrieval of data. The DDR WLCSP module under the TwiSTER line is produced with WLCSP technology, enabling steady data transmission and effective thermal reduction.

The following report shows that TwiSTER dual-channel memory module with 3,312MB/s data transfer rate in a dual-channel DDR system is 30% more efficiently than in a single-channel system.


This product line comes in 256MB and 512MB models, providing an ideal solution for over-clocking power users, gaming enthusiasts and business users alike. Products under the TwiSTER series use chips directly from upstream original suppliers, with 6-layer PCB and 30u gold-finger plating integrated into them. Circuitry design follows the JEDEC standard, which reduces electromagnetic interference, allows speedy and steady transmission of complex data and ensures security associated with the retrieval of large-sized data. All TwinMOS memory modules are provided under warranties that ensure customer support throughout the products’ lifecycle.

WLCSP: Wafer-level chip scale packaging, refers to the packaging of the entire wafer instead of individual chips diced from the wafer -- a technique producing packaged chips 20% larger than the original. WLCSP involves packaging the entire wafer before the dicing process, producing packaged chips the same size as the original.
