In August 2018, amd announced to hand over all orders of 7Nm CPU to TSMC, and the cooperation between the two sides has been very close in the past two years. In contrast,GF, AMD's ex girlfriend, is moving away from x86 CPU foundry, and now they claim to be the leader in MRAM。
In 2009, amd split the semiconductor manufacturing business and established global foundries (GF) company. Since then, amd has become a fabless wafer company. The chip production is mainly entrusted to GF foundry. Then, amd continuously reduced its shares and has no shareholding relationship with GF. The latter is now a wholly-owned subsidiary of Mubadala investment.
Thanks to this historical relationship, GF company has been called AMD by players
GF quickly disposed of many unprofitable wafer factories in recent years, including fab3e in Singapore and Fab 10 in New York State, etc., the focus of enterprises has also shrunk to some emerging areas, such as RF, MRAM memory chips, etc.
In the past few days, lattice core also announced that it has completed the development of 22fdx (22nm fd-soi) technologyThis technology is used to produce embedded magnetoresistive nonvolatile memory (emram).
Global foundries said it uses its 22fdx and emram technology to produce test chips, During ECC shutdown mode, at -40。
MRAM is a kind of future memory chip that may unify memory and flash memory. The future is star sea. However, it is mainly used in the Internet of things, vehicle electronics and other markets. It has small capacity, high reliability, high temperature and low temperature resistance.
Recently, lattice core said that it would be a leader in the field of MRAM, dedicated to helping customers develop differentiated products with rich functions and promoting the development of new technologies such as potential new computing architecture.
