SMART Modular this month demonstrated one of the industry’s first prototypes of a EDSFF 3-inch DDR4 Gen-Z memory module. The ZMM supports advanced functionality enabled by the new interface and offers throughput akin to that offered by today’s DDR4-4000 memory modules. SMART Modular’s 256 GB ZMM uses Samsung’s 32 Gb 4-high DDR4 DRAM devices as well as IntelliProp’s Gen-Z Mamba memory controller ASSP, which supports multiple access semantics, including byte and block addressable DRAM access, in-band configuration, and access key/region key memory isolation opcodes in a bid to simplify memory access needed to handle emerging data-centric workloads. The controller features 16 Gen-Z lanes with 25 Gbps PHY as well as 400 Gbps aggregate performance. The chip requires up to 20 W of power, so it...
