K4B4G1646D-BYMA – DDR3L SDRAM – Samsung
The Samsung K4B4G1646D-BYMA is a 4Gb DDR3L SDRAM (D-die) organized as 256M x 16, rated at DDR3L-1866 in a 96-ball FBGA package with 1.35V operation. This obsolete, hard-to-find memory device is available now from Pacific Component Xchange on an RFQ basis.
The Samsung K4B4G1646D-BYMA is a 4-gigabit DDR3L SDRAM device built on Samsung’s D-die process. It is organized as 256Mbit x 16 I/Os across 8 internal banks and supplied in a space-efficient 96-ball FBGA package. The “BY” designator identifies the low-voltage 1.35V DDR3L variant, and the device supports JEDEC double-data-rate operation up to DDR3L-1866. As a now end-of-life part, the K4B4G1646D-BYMA is frequently required for repair, replenishment, and end-of-line builds where the original Samsung component must be matched exactly.
