Intel resumed its position as the leading chip vendor as the downturn in the memory market negatively impacted many of the top vendors, including Samsung Electronics, Gartner's top vendor by revenue in 2018 and 2017.
"The memory market, which accounted for 26.7 percent of semiconductor sales in 2019, experienced a 31.5 percent decline in revenue in 2019," said Andrew Norwood, research vice president at Gartner, in a statement.
The DRAM segment declined 37.5 percent due to an oversupply caused by a fall in data center demand. Excess inventory resulted in decline in the average selling price of 47.7 percent in 2019, according to Norwood.
Intel was not hit as much as Samsung by the decline in the memory market but had its own problems with a constrained manufacturing capability and processor supply and its decision to sell its cellular modem business to Apple (Report: Apple in talks to buy Intel modem business).

As a result Intel's semiconductor revenue declined 0.7 percent in 2019. Samsung's memory revenue, which accounted for 82 percent of its sales, declined 34 percent in 2019.
NAND flash experienced a milder 2019 downturn than the overall memory market, with a revenue decline of 23.1 percent due to elevated levels of inventory at the end of 2018 and sluggish demand in the first half of 2019. Prices started to rise in the 2H19. Gartner expects the recovery in the NAND flash memory market to continue in 2020 with low growth in the bit supply and strong demand from solid-state drives and the ramp up of 5G smartphones.
