K4B4G1646E-BYMA – DDR3L SDRAM – Samsung

Samsung K4B4G1646E-BYMA is a 4Gb DDR3L SDRAM (E-die) organized as 256M x 16 in a 96-ball FBGA package, rated for DDR3L-1866 operation at 1.35V. This part has been discontinued by Samsung and is available for RFQ from Pacific Component Xchange.

The Samsung K4B4G1646E-BYMA is a 4 Gigabit DDR3L (low-voltage DDR3) SDRAM from Samsung’s E-die family. It is organized as 256M x 16 (32M x 16 I/Os x 8 banks) and packaged in a 96-ball FBGA, making it well suited for x16 memory subsystems in embedded, networking, and industrial designs. The device supports a maximum data rate of 1866 Mbps/pin (DDR3L-1866) at a 933 MHz clock and operates from a 1.35V (1.28V to 1.45V) supply for reduced power consumption versus standard DDR3.
