SK hynix detailed its memory-centric artificial intelligence architecture on Nov. 13, pairing Compute Express Link dynamic random-access memory pools with subsidiary Solidigm's high-capacity solid-state drives to ease data center bottlenecks.

The architecture introduces a 256-gigabyte CMM-DDR5 module that delivers 80 gigabytes per second of bandwidth over the CXL 3.2 interface. The design cuts memory module power consumption by roughly 30% compared with prior CXL iterations.
