Abstract(in English) | Tunnel leakage currents become the dominant from of leakage as MOS technology advances. An electric-field-relaxation scheme that suppresses these currents is described. Cosmic-ray-induced multi-errors have now become a serious problem at sea level. An alternate error checking and correction architecture for the handling of such errors is also described, along with the application of both schemes in an ultra-low-power 16-Mbit SRAM. A test chip fabricated by usign 0.13-μm CMOS technology showed. per-cell standby-current values of 16.7fA at 25℃ and 101.7fA at 90℃. The chip provided a 99.5% reduction in soft errors under accelerated neutron-exposure testing.. |
