Abstract
A 0.7-pJ/bit, 8.5-Gb/s/link inductive coupling inter-
chip wireless communication interface for a 3D-stacked static-
random access memory (SRAM) has been developed in a 7-nm
FinFET process. A new physical placement method that allows
coils to be placed over off-the-shelf SRAM macros with small
magnetic field attenuation, together with the use of synchronous
communication using Manchester encoding and a clocked com-
parator to enable the detection of small-swing signals, achieves
a 26% reduction i
