K4B4G1646E-BYMA000 – DDR3L SDRAM – Samsung

The Samsung K4B4G1646E-BYMA000 is a 4Gb DDR3L SDRAM (E-die) organized as 256M x 16, housed in a 96-ball FBGA package. This discontinued device is available for RFQ from Pacific Component Xchange.

The Samsung K4B4G1646E-BYMA000 is a 4-gigabit DDR3L SDRAM memory device built on Samsung’s E-die process. It is organized as 256M x 16 (32M x 16 I/Os x 8 banks) and supplied in a compact 96-ball FBGA package, making it a common building block for embedded systems, networking equipment, and graphics/display subsystems that require x16 DDR3L memory.

As a low-voltage DDR3L part, this device operates at a nominal 1.35V supply while remaining backward-compatible with 1.5V DDR3 designs, helping reduce system power in space-constrained applications. Samsung has discontinued this product, which makes it increasingly difficult to source through authorized distribution channels.
