Over 70% of its employees are engineers working on various research and development related projects. CXMT uses its 10G1 process technology (aka 19 nm) to make 4 GB and 8 GB DDR4 memory chips. It has licensed intellectual property originally created by Qimonda. [15] LPDDR4 RAM was added to the product portfolio in 2020. [16]
The DDR4 SDRAM is a high-speed dynamic random-access memory internally configured as 16 banks, 4 bank groups with 4 banks for each bank group for ×4/×8 and 8 banks, 2 bank groups with 4 banks for each bank group for ×16 DRAM. The DDR4 SDRAM uses an 8n prefetch architecture to achieve high-speed
Lexar Professional 2000x 64 GB SDXC UHS-II card. Lexar International is a brand of flash memory products, formerly American-owned, now manufactured by the Chinese memory company, Longsys. The Lexar "JumpDrive" trademark was often used synonymously with the term USB flash drives when the technology was first adopted.
A DIMM (Dual In-Line Memory Module) is a popular type of memory module used in computers. It is a printed circuit board with one or both sides (front and back) holding DRAM chips and pins . [ 1 ] The vast majority of DIMMs are manufactured in compliance with JEDEC memory standards , although there are proprietary DIMMs.
