DDR3L

i.MX 6ULL has a dedicated DDR memory controller which supports 16-bit LP-DDR2-800, DDR3-800, and DDR3L-800, all of which can operate up to 800 MT/s data rate. This design is provided with single 4-Gb x16 (512 MB) DDR3L memory. Micron’s MT41K256M16TW-107:P is a 4-Gb DDR3L SDRAM used in this design. The memory interface comprises of single channel of 16-bit data signals, along with command and address signals. The DDR interface is shown in Figure 2.
