Mobile DRAM

Low Power DDR2 SDRAM

Low Power DDR2 SDRAMs (Low Power Double Data Rate SDRAMs 2nd generation) are memories with 1.8/1.2 V 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.
