Mobile DRAM

Low Power DDR4/4X SDRAM

Low Power DDR4/4X SDRAMs (Low Power Double Data Rate SDRAMs 4th generation) are memories with 1.8/1.1/1.1 V (DDR4) or 1.8/1.1/0.6 V (DDR4X) power supply, designed with specific features to reduce power consumption.
All ICs are RoHS compliant.

* Status: P - mass production, S - samples, UD - under development, N - not recommended for new design.
