Winbond Electronics and Macronix International have reported sequential growths in March revenues of 12.7% and 10.6%, respectively.

Compared to a year ago, Winbond's consolidated revenues for March 2013 declined 2.6% to NT$2.71 billion (US$90 million). Accumulated sales for January to March came to NT$7.68 billion, up 2.5% from the same period of 2012.

Market watchers expect Winbond to return to profitability in the first quarter of 2013, thanks to a recovery in DRAM prices and the firm's process transition enabling lower production costs. Winbond experienced a sixth consecutive quarterly loss in the fourth quarter of 2012.

Macronix announced consolidated revenues of NT$1.46 billion for March 2013, up 10.6% sequentially but down at the same rate on year. Accumulated consolidated sales for January to March were NT$4.405 billion, a decrease of 14.4% compared to the same period of 2012.

Macronix is aiming to return to profitability in the third or fourth quarter of 2013. The firm experienced a fourth consecutive quarterly loss in fourth-quarter 2012.

Winbond manufactures niche-market DRAM and NOR flash memory, while Macronix specializes in NOR flash and mask ROM chips.
