K4B4G1646D-BHMA – DDR3 SDRAM – Samsung

The Samsung K4B4G1646D-BHMA is a 4Gb DDR3 SDRAM in a 96-ball FBGA package, organized as 256M x 16 and rated for DDR3-1866 operation at 1.5V. This obsolete, hard-to-find memory device is available for RFQ at Pacific Component Xchange.

The Samsung K4B4G1646D-BHMA is a 4-gigabit (4Gb) DDR3 SDRAM device from Samsung’s K4B4G1646D D-die family. It is organized as 256M x 16 and supplied in a 96-ball FBGA package, rated for DDR3-1866 data-rate operation at a standard 1.5V supply. As a JEDEC-standard DDR3 component, it served as a high-density, high-bandwidth main-memory device across PC, embedded, networking, and industrial designs. Samsung has discontinued its DDR3 product line, making this part an end-of-life device that is increasingly difficult to source through authorized channels.
