Abstract :
An AC-coupled 3D memory interface for chip-to-chip communication is implemented in 90 nm CMOS technology. It transfers 128 bit words between stacked SRAMs in an ARM-based System on Chip (SoC) platform at 250 MHz. This interface requires 0.05 mm2 of occupation area and achieves a 32 Gbit/sec of throughput and an average energy consumption of 35 muW/Gbit/sec.
