Samsung Electronics is planning to curtail growth in memory chip output next year to keep supplies tight amid an expected slowing in demand, according to people briefed on the matter. The move would help maintain or drive up semiconductor prices, the people said, asking not to be identified discussing the plan. Samsung now expects bit growth of less than 20 per cent for dynamic random-access memory (DRAM) chips and a rise of 30 per cent for NAND flash, the people said. Bit growth, which refers to the amount of memory produced, is a key barometer for gauging market demand. Samsung said earlier this year that it expected increases of 20 per cent for DRAM and 40 per cent for NAND in 2018. China probes dominant DRAM chip makers – Samsung Electronics, SK Hynix and Micron The semiconductor industry is notorious for its boom and bust cycles, and investors have grown increasingly concerned that Samsung and its peers are headed for a downturn, as demand softens after years of record profit. If Samsung, the world’s biggest producer of NAND and DRAM, trims its production, that may help prop up prices for the company along with SK Hynix and Micron Technology. “There are only three major players left and they have the power to control supplies,” said Park Sung-shin, a fund manager at KTB Asset Management. Samsung shares fell about less than 1 per cent in Seoul. Just hours earlier, Micron, the largest US maker of memory chips, gave a revenue forecast that fell short of analysts’ estimates, adding to concern that a two-year surge in demand for its products is fading. US memory chip maker Micron says Chinese officials visited its offices ‘seeking information’ in possible new trade war front “We’re flexibly managing capacity in line with the market supply-demand situation,” Samsung said in a text message. While limiting chip supply may buoy chip prices, that would mean Samsung and its rivals cut back on investment, such as orders for equipment and materials. Suppliers to chip producers include Applied Materials and Lam Research Corp. Semiconductors are the biggest and most profitable business for Samsung, as it produces chips for its own devices and sells to other smartphone makers. The chip division generated operating income of 35.2 trillion won (US$31.4 billion) in 2017, more than doubling from a year earlier, which helped drive the company’s earnings to a record. “If Samsung does cut its DRAM bit growth, it shows the company is happy with the current oligopoly market structure,” said Anthea Lai, an analyst at Bloomberg Intelligence in Hong Kong. “It prefers keeping supply tight and prices high, rather than taking market share and risking lower prices, therefore chances for DRAM prices to stay strong is higher.” China’s long march for the soul of the nation’s digital future faces an ever-shifting end point Shares of Samsung had fallen 7.3 per cent this year through Thursday after reaching an all-time high in 2017. Micron’s stock rose as much as 4.8 per cent in New York trading following the Bloomberg report. Western Digital Corp, which owns part of a joint venture with Toshiba Corp in flash memory, rose as much as 3.9 per cent. Earlier this month, analysts at Morgan Stanley led by Shawn Kim predicted a weakening outlook for server DRAM and cautioned on a build-up in inventories. Industry DRAM bit volume rose 20 per cent in 2017, just half the 40 per cent rate of 2016, according to IC Insights. While servers have fuelled demand for memory, stalling smartphones sales around the world have raised concerns about market growth for semiconductors. In addition to semiconductors, Samsung produces Galaxy smartphones and organic light-emitting diode screens used in Apple’s iPhones.
