Bringing 3-D devices based on through-silicon via (TSV) is taking longer than expected. But at ISSCC, Samsung announced the development of a 1-Gbit DRAM with a 512-pin wide I/O interface intended for mobile applications such as smartphones and tablet computers. The chip is implemented in a manufacturing process technology somewhere between 50- and 59-nm. It will be reportedly housed in a 3-D package, based on TSV technology. Shipments are targeted for 2013. ''The wide I/O memory interface enabled by TSV technology offers considerable power reduction (up to 75 percent) by reducing the load capacitance of interconnect and I/O circuits,’’ Kwon said.
