Samsung Electronics has succeeded in shrinking to one quarter of its previous size a type of memory chip commonly used in mobile telephones and other handheld electronic devices, the company has announced.
The company, which is one of the world's largest memory chip makers, said in a statement that it has applied tape ball grid array (TBGA) technology to 8Mbit versions of SRAM (synchronous random access memory) chips to shrink them to a volume of 63 square millimetres. TBGA technology allows designers to do away with bulky internal printed circuit boards and use a much thinner polymide tape to link the actual chip to the connectors, or package legs, that link onto the circuit board.
As portable devices become more and more complex, designers are continuously striving to reduce the size, weight and power consumption of components used inside the devices. By reducing the memory volume, devices can be either made smaller or hold increased memory in the same size case.
Sample shipments of the new chips will be available from April, said the company. It said it expects the worldwide market for 8Mbit SRAM chips to be worth $US300 million this year and $600 million in 2001.
