New memory technologies impact semi cleanrooms

摘要

Austin, Texas—Freescale Semiconductor Inc. (www.freescale.com) has embarked on a memory technology—magnetic tunnel-junction random access memory, or MRAM—that is proving to have implications for manufacturing in Freescale's own cleanrooms. Another memory alternative, ferro-electric RAM, or FRAM, is already in production, and both could impact semiconductor cleanrooms throughout the industry. While Freescale doesn't make stand-alone memory chips, it inserts considerable storage into its automotive and consumer-embedded products. Embedded memories can run the gamut of technologies—from DRAM and SRAM to flash—which can add to product development compl
