Nanya Technology Corp. (Nanya), Taiwan's top DRAM chip-maker, yesterday reported consolidated monthly revenue of NT$3.63 billion for March, its highest mark since June 2011.
The monthly revenue increased 18.16 percent month on month and 22.16 percent year on year
 The company's non-consolidated revenue also hit a two-year high. First-quarter consolidated revenue reached NT9.24 billion, increasing 22.29 percent from the fourth quarter of last year.
Nanya said its sales price and volume both increased significantly in March due to high demand for tablet computers. Shipments increased 6.6 percent from February while the average sales price jumped 12 percent last month.
Given the escalating tension on the Korean Peninsula, which has given rise to a market expectation of price hikes, DRAM prices would continue to go up in the short term, said Nanya. In the long term, demand would continue to exceed supply, the company added.
 DRAM, or dynamic random access memory, is the most common type of random access memory for personal computers and workstations.
 Winbond Electronics Corp., another major memory chip-maker in Taiwan, posted monthly revenue of NT$2.71 billion for March, or a 12.7-percent increase month on month.
The company's first-quarter consolidated revenue totaled NT$7.67 billion, or a 2.52-percent increase year on year. It has reported a loss for a second consecutive year.
According to an institutional investor forecast, the company's gross profit margin has been going up in recent quarters and would turn a profit in the second quarter at the earliest.
 The strong performance of these two chipmakers was propelled by recent surging demand for DRAM, which has led to price hikes because of supply shortages, according to industry analysts.
Driven by demands from the launching of various tablet computer brands in China, DRAM prices are expected to go up for the time being. The price of 4-gigabyte DRAM may rise an additional 30 percent to reach NT$30 per unit, as the high season for the mobile device market nears, said industry analysts.
