Non-DRAM specialist Winbond Electronics saw its March revenues increase 14.6% sequentially, while revenues at fellow company Macronix International declined 11.8% on month.

Winbond generated revenues of NT$ 2.15 billion (US$72.9 million) in March, up from NT$1.88 billion in February. But the figure shows a 9.3% decrease compared to the NT$2.37 billion posted in March 2011.

Winbond's revenues amounted to NT$5.81 billion for the first three months of 2012, slipping 18.8% from NT$7.16 billion a year ago.

Winbond reported net losses for the last two quarters of 2011 as falling prices for NOR flash and specialty DRAM memory dragged down company sales. Market watchers expect Winbond to return to profitability in the second quarter of 2012 as product ASPs and orders recover.

Macronix collected NT$1.6 billion in March revenues, down 11.8% on month and 20.8% from the same period of 2011. Revenues totaled NT$5.08 billion for the first three months of 2012, a decrease of 22.7% from a year earlier.

Macronix attributed the 11.8% sales drop to fewer-than-expected orders for its mask ROM memory from Japan-based clients as well as unfavorable NOR flash prices. Macronix' first-quarter sales came below its targeted NT$5.2-5.8 billion.

Macronix reportedly supplies ROM chips for Nintendo's game consoles.
