Despite revenue decline, Samsung Electronics has further upped its leadership in the global NAND flash market in the fourth quarter of 2020, a report showed on Wednesday. The South Korean tech giant, also the leader in the DRAM sector, had a 32.9 per cent share of the global NAND flash market in terms of revenue in the October-December period, up 1.5 percentage points from a quarter earlier, according to market tracker TrendForce. But Samsung s revenue from NAND flash products came to a total of US$4.64 billion in the last three months of 2020, down 3.4 per cent from a quarter earlier. Samsung s NAND flash bit shipments rose by 7-9 per cent quarter-on-quarter on strong procurements from the smartphone and PC segments, according to TrendForce, but its average selling price (ASP) of NAND flash products declined by more than 10 percent from the previous quarter.
