Bringing to a close an investigation that began in January 2007, the South Korea Fair Trade Commission (FTC), has concluded there is no evidence of collusion to fix prices in the NAND flash memory industry.

The FTC was investigating the world’s four largest manufacturers of NAND flash memory: two in South Korea, one in Japan, and one in the United States. The four companies investigated are unnamed in the report, leaving us to wonder who they are. The report, however, does tell us the world’s four largest NAND flash memory manufacturers are Samsung and Hynix (in South Korea), Toshiba (in Japan), and SanDisk (in the United States). Perhaps it’s not such a mystery after all.

NAND flash memory, which is cheap to produce, is used in digital music players, digital campers, USB memory sticks, and the like. An over-production in the latter part of the decade lead to a downward spiral in prices, which some manufacturers are alleged to have perpetrated to gain market share. Manufacturers claim that pricing was more a factor of oversupply and technological advances, which the FTC seems to agree with, finding no evidence of price-fixing on the international level, and limited evidence of price-fixing on the domestic level.
