As DRAM contract prices have risen month by month, spot market quotes are expected to rebound in July and exceed contract prices in the fourth quarter of 2012, according to chairman and CEO Simon Chen for memory module maker Adata Technology.

Following Micron Technology's merger with Elpida Memory, global DRAM production will be dominated by Micron, Samsung Electronics and SK Hynix, with the reshuffling conducive to stable global supply of DRAM, Chen said. However, Taiwan-based PC vendors may fall at a disadvantage regarding procurement, according to industry sources.

Adata expects its revenues for the second quarter to decrease less than 3% and and gross margins to remain unchanged on quarter, Chen indicated.

Chen holds a conservative outlook on the NAND flash market in the second half of 2012, saying that makers' expanding production and NOR flash makers' shift to NAND flash will result in global oversupply. The increase in global demand for NAND flash in the second half of 2012 will hinge on Apple's procurement, Chen said.

In response to the opinion that ultrabooks may increase demand for NAND flash in the second half of 2012, Chen indicated that a substantial increase in demand will occur if retail prices for ultrabooks fall to US$399, lower than the US$599 target of PC vendors.

Adata will focus its future on SSDs, eMMC and server memory, Chen said.
