CXMT Says Fifth-Generation Memory Platform Enters Mass Production
CXMT is a Chinese company that makes memory chips.
It said a new fifth-generation platform has started mass production.
DRAM is a type of short-term memory that phones and computers use to run programs.
CXMT says its new platform can make more powerful chips while using less electricity and costing less.
The platform fits the data-storage parts closer together on each chip.
CXMT also announced two new products for smartphones and other portable devices.
Each product can store 24 gigabits of data.
The company says the platform can produce at least 50% more chip dies from each wafer than its previous platform.
This could give electronics companies another chip supplier and strengthen China’s competition with major memory-chip producers.
CXMT said its fifth-generation DRAM technology platform entered mass production on Sunday.
The platform is designed to produce more powerful chips at lower cost and with less power use.
CXMT reduced key data-storage feature spacing to 11.95 nanometres using quadruple patterning.
The company said the platform can produce at least 50% more gross chip dies per wafer than its predecessor.
CXMT also began mass production of two 24-gigabit LPDDR5X products for smartphones and portable devices.
- Who
- CXMT, a Chinese DRAM chipmaker, led by vice president Luo Xiaodong in the cited announcement.
