H5CG44AHBDX018N – DDR5 SDRAM – SK Hynix
SK Hynix H5CG44AHBDX018N is a 16Gb DDR5 SDRAM memory IC organized as 4Gx4 (x4) and rated at DDR5-6400. Available now for RFQ from Pacific Component Xchange.
The SK Hynix H5CG44AHBDX018N is a 16-gigabit (16Gb) DDR5 SDRAM memory component from SK Hynix’s H5CG4 DDR5 device family. It is organized as 4Gx4 (x4 data width) and is built for the high-bandwidth, low-power requirements of modern DDR5 platforms. As a x4 DDR5 device, it is commonly used as a building block for high-density server and workstation memory modules such as RDIMMs and LRDIMMs.
Decoded from SK Hynix’s DDR5 component nomenclature, the H5CG44AHBDX018N designates a DDR5 SDRAM IC (H5C), 16Gb density (G4), x4 organization (the following 4), an A-die revision with commercial (0 to 95C) temperature support, and an HB speed code corresponding to a DDR5-6400 speed grade. Like all JEDEC DDR5 SDRAM, it operates at a 1.1V supply (VDD/VDDQ) with a 1.8V VPP rail, and incorporates on-die ECC, an 8 bank-group / 32-bank architecture, and decision-feedback equalization (DFE) for signal integrity at high data rates.
