Inotera Memories, Nanya Technology and Rexchip Electronics have all reported increases in October 2011 revenues from the previous month, while Powerchip Technology posted a drop.

Inotera's revenues for October 2011 grew 3.8% on month to NT$2.99 billion (US$99 million), while Nanya's rose 8.5% to NT$2.79 billion. Changes in product mix resulted in higher revenues for both companies.

Inotera and Nanya said previously they would boost non-standard DRAM output ratios to mitigate the impact of stagnant PC sales.

Nanya's October sales were also driven by more stable contract pricing. New figures from DRAMeXchange show that late October contract prices for both 2GB and 4GB DDR3 modules went flat. Prices saw narrower drops since September.

Inotera's 2011 sales through October reached NT$31.68 billion, down 11.1% from a year ago, while Nanya suffered a larger 33% decrease during the period.

Rexchip, the production subsidiary of Japan's Elpida Memory, saw its October revenues rise almost 20% sequentially to NT$1.96 billion. Sales were driven by more output and favorable pricing.

Elpida recently revealed plans to move some of its in-house production to Rexchip Electronics. Company CEO Yukio Sakamoto was quoted as saying in previous reports the Taiwan subsidiary would play an increasingly important role in Elpida's DRAM supply to customers worldwide.

Powerchip generated revenues of NT$2.12 billion, down 4.7% on month. The company has reduced its DRAM output significantly while expanding production of non-DRAM products on an OEM basis.
