3D NAND market share to grow 5.2 per cent in 2014

IHS has reported that by 2017, nearly two-thirdsor 65.2 per centof all NAND memory chips shipped worldwide will be produced using 3D manufacturing processes, up from less than one per cent this year. The share of the overall NAND market accounted for by 3D technology is forecast to jump to 5.2 per cent in 2014, and then surge to 30.2 per cent of total flash memory shipments in 2015. In 2016, 3D NAND will enlarge its market share to 49.8 per centrepresenting about half of the entire flash memory market, added the market research company.

"There's widespread agreement that just one or two generations may be left before NAND flash made using conventional planar semiconductor technology reaches its theoretical limit," said Dee Robinson, senior analyst, memory and storage for IHS. "As lithographies shrink further, performance and reliability may become too degraded for NAND to be used in anything but the very lowest-cost consumer products. Because NAND suppliers are compelled to continue building products with higher densities and lower prices, they will migrate to 3D manufacturing quickly in the coming years."

A major factor driving NAND makers to keep improving their products is demand from products such as media tablets and smartphones. These devices are demanding higher capacity and less expensive storage of content, including pictures, music and video.

Historically, NAND flash makers have employed miniaturisation to increase the capacity and reduce the costs of their products. Miniaturisation is the process of shrinking the NAND flash cells with each successive technology generation, allowing suppliers to fit more bits on each silicon wafer.

With 3D technology, the emphasis shifts away from miniaturisation and towards increasing density by layering NAND flash cells on top of each other. This will be the most cost-effective way of pushing NAND to the next level because most of the existing manufacturing equipment can continue to be used, minimising expenses while maximising return on investment.

Samsung and SK Hynix, the biggest players in the global memory trade, announced their initiatives in 3D NAND in August during the Flash Memory Summit in Santa Clara, Calif.

Samsung said commercial production of V-NAND, the company's name for its 3D flash memory products, started during Q2. The end product will be a V-NAND-based solid-state drive, in 480GB and 960GB densities, initially targeting the enterprise market. V-NAND, Samsung said, will be more reliable than 1x-nm NAND, consume less power and also deliver higher performance in sequential as well as random writes.
