The DRAM electronic chip market can expect three profitable years after its worst ever slump, industry research firm DRAMeXchange said on Tuesday, citing a recovering global economy and limited capacity expansion.

The research house said the dynamic random access memory market will be helped also by corporate PC replacements and consumer demand stimulated by Microsoft's new Windows 7 operating system. DRAM chips are used mostly in personal computers.

According to research firm iSuppli DRAM chip sales will grow 41 percent this year, to $31.9 billion.
