VTCMOSVariable Threshold-voltage CMOS, 1996
-
VTCMOS (Variable Threshold-voltage CMOS)
-
VTCMOS is a low power circuit technology which uses substrate bias effect to dynamically control the threshold voltage (Vth) of a transistor. We can achieve significant power reduction by raising Vth to reduce leakage when the system is in standby, and lowering Vth and the supply voltage when the system is active.
VS方式Variable Supply-voltage scheme, 1997
-
VS (Variable Supply-voltage) Scheme
-
VS Scheme is a low power circuit technology that employs an on-chip DC-DC convertor to dynamically control on-chip supply voltage. By dynamically adjusting the supply voltage in response to changing system performance requirements, we enable optimal tradeoff between operating speed and power consumption.

TCI (ThruChip Interface)
-
TCI is a 3D integration technology that employs inductive coupling between coils created with on-chip metal line patterns for data communication across stacked chips. It realizes the same or better performance as TSV (Through Silicon Via) but at a lower cost. By thinning the silicon chips, we can achieve exponential improvement in cost performance.

DRS (Digital Rosetta Stone)
-
DRS is an ultra-long retention digital storage technology based on wireless charging and TCI. With DRS technology, digital data is first written into mask ROM on silicon wafers which are then sealed and waterproofed. Data retrieval is realized contactlessly using wireless charging and TCI. It is a proposal of a long-term storage solution necessary for the preservation of our cultural heritage in digital form.
TLCTransmission Line Coupler, 2013
-
TLC (Transmission Line Coupler)
-
TLC is a contacless connector technology based on electromagnetic coupling between transmission lines. It enables small and light-weight connector design, high speed data transmission, and improves waterproof property, resistance to vibration, as well as electromagnetic compatibility. When applied to mobile systems and automobiles, it enables system implementation using LEGO block-like modules.
