SK hynix completes customer validation of DDR5 memory chips

SEOUL, April 23 (Yonhap) -- SK hynix Inc. said Wednesday its 96 gigabyte double data rate 5 (DDR5) memory chips have passed customer validation, marking a key step toward production readiness.

The new product, known as CMM-DDR5, is a dynamic random access memory (DRAM) solution for data center servers.

When integrated into server systems, it can process data at speeds of up to 36GB per second. Compared to earlier DDR5 modules, the new chips offer a 50 percent increase in capacity and a 30 percent improvement in bandwidth performance, according to SK hynix.

It is based on Compute Express Link (CXL) 2.0 technology, a next-generation interface that efficiently connects central processing unit (CPU), graphic processing unit (GPU), memory and other components in high-performance computing systems to support massive, ultra-fast computation.

SK hynix said it is also proceeding with the validation process for a 128GB product with another customer.

The company plans to complete the ongoing 128GB validation as soon as possible to establish a CXL product portfolio to support customers in a timely manner.
