K4B4G1646E-BCNB0 – DDR3 SDRAM – Samsung

Samsung K4B4G1646E-BCNB0 is a 4Gb DDR3 SDRAM (E-die) organized as 256M x 16, rated at DDR3-2133 speed, 1.5V, in a 96-ball FBGA package. An obsolete, hard-to-find DRAM available through Pacific Component Xchange by RFQ.

The Samsung K4B4G1646E-BCNB0 is a 4-gigabit DDR3 SDRAM built on Samsung’s E-die process. It is organized as 256M x 16 across 8 internal banks and is rated for the DDR3-2133 speed grade at a 1.5V supply, supplied in a space-efficient 96-ball FBGA package. This x16 device is a common building block for memory subsystems in embedded computing, networking, and consumer electronics where high bandwidth is needed in a single-chip footprint.

Samsung has discontinued the K4B4G1646E family, making the K4B4G1646E-BCNB0 an end-of-life component that is no longer available through authorized distribution. Pacific Component Xchange specializes in sourcing exactly this type of obsolete and hard-to-find memory to keep mature designs and long-lifecycle products in production.
