Abstract :
A 1.6Gb/s/pin 1Gb DDR3 SDRAM with a CAS latency of 8 at 1.5 V is developed using an 80 nm dual poly CMOS process, which consumes 30 mA of IDD2N and 160 mA of IDD4R. With an address queuing scheme and a self-timed IOSA, IDD4R current can be reduced by 18 mA. To achieve 1.6Gb/s/pin operation, a bang-bang jitter free DLL with a split phase interpolator is employed.
