INTEL Corporation of the United States, the world's largest computer chip manufacturer, is to make an equity investment in a $1.3 billion plant under construction in Texas by Samsung, the South Korean electronics giant said yesterday.

Samsung, a manufacturer of Dynamic Random Access Memory (DRAM) chips, will provide Intel with memory products and will retain full operational and technological management of its new facility. The company said the factory was scheduled to begin production in late 1997 and would turn out some 25,000 wafers - chip components - a month when it reached its full capacity.
