DRAM firm Nanya Technology has reported almost flat revenue growth for May 2012, with sales rising just 0.3% on month to NT$3.42 billion (US$113.9 million).

Revenues at Inotera Memories, Nanya's manufacturing joint venture with Micron Technology, registered a 9.7% sequential increase to NT$3.29 billion in May, according to company data.

Compared to a year ago, however, both May figures represent over 10% declines. Nanya's May revenues were 12.7% less than the NT$3.92 billion posted in May 2011, while Inotera's showed a 10.3% decrease.

Inotera said previously that bit shipments for the second quarter would climb 30-35% sequentially, while Nanya estimated a modest increase.

In other news, both Nanya and Inotera have moved to diversify their offerings. Nanya saw its non-PC DRAM products account for 50% at the end of 2011. The proportion will expand further in 2012, the company said. Nanya has shifted its focus to shipping products for consumer electronics, servers and mobile devices.

Inotera expects the shipment ratio for non-PC DRAM to reach 50% by the middle of 2012. The firm has ramped up server DRAM production using 30nm-class process technology, and plans to enter the mobile DRAM field in the second half of 2012.
