Winbond Electronics has reported flat sequential growth in June revenues, while fellow NOR flash company Macronix International saw its June sales slip 4.8% on month.

Winbond generated revenues of NT$2.28 billion (US$76 million) in June 2012, however, showing a decrease of 2.1% on year. Second-quarter revenues totaled NT$12.6 billion, rising 14.5% on year but essentially flat with the prior quarter.

Including sales generated by logic IC subsidiary Nuvoton Technology, Winbond's consolidated revenues slid about 0.6% on month and 1.7% from a year earlier to NT$3.03 billion in June 2012. Consolidated sales for the first half of the year came to NT$16.56 billion, a 10.6% decline compared to the same period of 2011.

Winbond manufactures niche-market DRAM and NOR flash memory. Company president Tung-Yi Chan stated previously that Winbond would raise the sales ratio for its NOR products to 60% from the current 40%.

Winbond experienced a third consecutive quarterly loss in the first quarter of 2012. The firm said it is aiming to return to profitability during the second half of the year.

Macronix is also eyeing a return to profitability in the third or fourth quarter of 2012. The maker of NOR flash and mask ROM memory swung to net losses in the first quarter on falling orders and chip ASPs.

Macronix announced June revenues of NT$1.95 billion. Revenues for the first six months of 2012 amounted to NT$10.88 billion, down 15.5% from a year ago.
