Samsung Electronics and Hynix Semiconductor, South Korea's two largest chip companies and leaders in memory IC sales, have said they plan to co-develop and standardize spin-torque-transfer magnetic-random-access-memory (STT-MRAM) chips, and become the industry leaders in the processing of chips on 450-mm wafers, according to reports.

Chip designer Rambus Inc. has asked a federal judge in San Jose to rule that Hynix Semiconductor Inc. can't sell chips in the US. Rambus has filed similar suits against Samsung Electronics Co. and Boise, Idaho-based Micron Technology alleging they conspired to fix prices for memory chips.
