CXMT reports progress on denser memory chip design
China’s memory chip maker ChangXin Memory Technologies, or CXMT, says it has made progress on a new memory-cell design.
The company announced the development at an industrial event in Shanghai.
Samsung Electronics and SK Hynix are also pursuing the same type of structure.
CXMT’s design uses a 4F square layout, where F refers to the minimum line width of a semiconductor.
Mainstream commercial DRAM currently uses a 6F square layout, which takes more area for each memory cell.
Fitting more cells onto a chip could increase its storage density, and CXMT says the design could also improve efficiency.
CXMT plans to introduce a server-memory product based on the design by the end of 2026.
CXMT reported progress on a memory-cell structure designed to increase storage density.
The Chinese memory chip maker said the design could also improve efficiency.
The 4F square structure fits each memory cell into an area of four square F, where F is the minimum semiconductor line width.
Mainstream commercial DRAM currently uses a 6F square-cell structure.
CXMT plans to launch a server-memory product based on the design by the end of 2026.
Samsung Electronics and SK Hynix are also pursuing the structure.
