Prices of dynamic random access memory chips have jumped more than 10 percent in recent weeks amid concern that the key parts for personal computers could be in short supply, data showed Wednesday.

The fixed price of DDR3 2 Gigabit 256Mx8 1333MHz came to $0.92 in the first half of January, up 10.84 percent from $0.83 in the second half of December, according to the data by market researcher DRAMeXchange.

The chip was priced at $4.34 when it was launched in September 2010. Its price plunged to a record low of $0.8 in November, due to oversupply and a continued slump in the PC industry, but it has since rebounded for its second straight month.

Prices of other DRAM products also climbed, with DDR3 4 Gigabyte SO-DIMM 1333/1600MHz chips gaining 9.52 percent to $17.25 and the DDR3 2GB SO-DIMM 1333/1600MHz adding 8.33 percent to $9.75. (Yonhap News)
