K4B4G1646E-BCNB000 – DDR3 SDRAM – Samsung

The Samsung K4B4G1646E-BCNB000 is a 4Gb DDR3 SDRAM (E-die) organized as 256M x 16, rated for DDR3-2133 operation at 1.5V in a 96-ball FBGA package. This discontinued, hard-to-find device is available now for RFQ at Pacific Component Xchange.

The Samsung K4B4G1646E-BCNB000 is a 4-gigabit DDR3 SDRAM from Samsung’s E-die generation, organized as 256M x 16 across 8 internal banks. Built to the JEDEC DDR3 standard, the device operates from a single 1.5V (1.425V–1.575V) supply and is offered in a space-efficient 96-ball FBGA (x16) package, making it a common building block for graphics buffers, embedded systems, networking gear, and consumer electronics that pair memory directly to a controller or SoC.

The -BCNB speed code identifies the DDR3-2133 grade, the top data-rate bin documented for this E-die family, while remaining backward compatible with slower DDR3 timings such as DDR3-1600 and DDR3-1333. The -BCNB000 ordering variant is a standard configuration of this part. Samsung has discontinued the K4B4G1646E series, which makes verified, sourceable inventory increasingly difficult to obtain through authorized channels.
