ProMOS Technologies and Rexchip Electronics have announced growth in February 2011 revenues from the previous month, joining fellow DRAM companies Nanya Technology and Powerchip Technology that also enjoyed sequential increases.
ProMOS's revenues for February 2011 grew 4.4% sequentially to NT$1.32 billion (US$45 million). On an annual basis, revenues rose for the second straight month in February. Combined revenues for the first two months of 2011 reached NT$2.58 billion, up 4.8% on year.
ProMOS has long been speculated to be a potential target for Elpida Memory, which ProMOS is working closely with under a DRAM foundry agreement. ProMOS also uses Elpida's stack design to make its own-brand niche DRAM products.
ProMOS reportedly has shifted its focus from PC DRAM to memory products for mobile consumer applications, and is expanding its foundry services. The company is still using Elpida's 60nm-class process to produce chips, and needs more capital to purchase new equipment for process upgrades, according to a Chinese-language Apple Daily report.
Rexchip, a 64%-held subsidiary of Elpida, generated NT$3.37 billion in February revenues, a 56.8% rise from January levels. Compared to a year ago, however, Rexchip's revenues for February 2011 slid 15.1%.
Rexchip recently revealed plans to allocate about NT$3.6 billion for its transition to 30nm-class process technology in 2011. It now manufactures DRAM chips using Elpida's 40nm-class stack design.
