DRAM chipmakers Inotera Memories and Nanya Technology have both reported sequential decreases in consolidated revenues for January 2015, due to falling DRAM prices.

Consolidated sales at Inotera slid 2.5% on month to NT$6.74 billion (US$213 million). The figure also represents a decline of 6.6% compared to the same period in 2014.

Inotera indicated that the result for January 2015 might be revised as its major customer was unable to provide final pricing figures before the January sales results were published. According to local regulations, listed companies must report their monthly revenues by the 10th of each month.

Nanya generated consolidated revenues of NT$3.98 billion in January 2015, down 4.2% on month and 4.4% on year.

A seasonal slowdown in demand has dragged down DRAM prices recently. However, both Inotera and Nanya are optimistic about the market and their business outlook for 2015.

Inotera and Nanya saw their combined profits exceed NT$80 billion in 2014, which came above market expectations, buoyed by rising chip prices.
