Korean memory maker SK Hynix has developed what it claims is its first DDR5 dynamic random access memory (DRAM)-based compute express link (CXL) memory.

The company is sampling the slim enterprise and data center standard form factor (EDSFF) memory E3.S and it supports PCIe 5.0 x8 lane and uses DDR5 standard DRAM. It is also equipped with CXL controllers.

What is CXL?

CXL is based on the PCIe standard and is a new interface designed to help increase the efficiency of using CPUs, GPUs, accelerators and memory.

The idea is to create a memory that is expandable and flexible compared to current server market where the memory capacity and performance is fixed once the server platform is adopted.

VXL has the potential as an interface for high performance computing systems such as artificial intelligence and big data related applications.

SK Hynix’s first CXL memory device is a 96 GB product composed of 24 GB DDR5 DRAM based on 1 anm, the company’s latest tech node.

The server ecosystem including processor and compute makers are supporting the form factor including Dell, Intel, AMD, Montage and more.

SK Hynix said it plans to mass produce the CXL memory products by 2023. Prior to that, the company will demonstrate the memory at the Flash Memory Summit this month and at the Intel Innovation event in September.
