Abstract (in Japanese) (See Japanese page) 
(in English) A 90nm CMOS processor is mounted face down on a package by C4 bump and a 65nm CMOS 1MB SRAM is glued on it face up. The two chips under different supply voltages are AC-coupled by inductive coupling that provides 19.2Gb/s data link. Measured power and area efficiency of the link is 1pJ/b and 0.15mm^2/Gbps, which is 1/30 and 1/3 in comparison with the DDR2 interface respectively. Furthermore, multi-SRAM stacking incorporating a wire-penetrating technique and an open-skipped inductor scheme is successfully demonstrated.
