Macronix International and Winbond Electronics have reported sequential growth in revenues for April 2011 of 6.2% and 6.4%, respectively.
Macronix, a manufacturer of mask ROM and NOR flash chips, posted NT$2.15 billion (US$75 million) in April revenues. Revenues were 6.4% less than the NT$2.3 billion registered in April 2010.
Macronix accumulated NT$8.72 billion in revenues from January through April, showing a 1.6% decrease compared to the same period of 2010.
Macronix estimated revenues at NT$6.4-6.8 billion in the second quarter, compared with NT$6.6 billion in the first quarter. Growth in NOR flash sales will outperform that of ROM, the company said during a recent investors meeting.
Winbond, which makes niche-market DRAM and NOR chips, generated NT$2.53 billion in April revenues. The figure showed 6.4% growth on month but a 6.8% drop from NT$2.71 billion in April 2010.
Including sales generated by logic IC subsidiary Nuvoton Technology, Winbond's consolidated revenues for April 2011 slipped 6.15% from a year earlier to NT$3.25 billion. But the figure was almost 9% higher than the NT$2.98 billion posted in March.
Winbond's niche-market DRAM products include specialty DRAM and mobile RAM. The company also manufactures GDDR chips on an OEM basis.
