Rohm Co Ltd said at the end of last month that it would start mass producing ferroelectric random-access memory chips as early as next fiscal, which starts on April 1. The Kyoto-based firm plans to start producing 1,000 6 wafers per month in September and boost production to 10,000 next year. The parts, which retain their state without power, come in 14K-bit, 16K-bit and 64K-bit versions. Rohm says it will be the first Japanese firm to mass-produce FRAM chips, but what it didn’t say is that the technology is the creation of Colorado Springs-based Ramtron International Corp from which Rohm licensed it.
