DRAM

DDR4 SDRAM

High-speed Double-Data-Rate Synchronous DRAMs generation 4 which achieve greater data speed than DDR3 SDRAMs by higher clock rate at a lower supply voltage.
All Ics are RoHS compliant.

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