Abstract

JAZiO is a digital signal-switching technique that uses differential sensing but requires only a single pin per signal. It´s based on detecting change or no-change from the preceding state instead of the traditional higher low-voltage comparison to a reference. JAZiO is suitable for low-latency, burst-mode operations for high-speed inter- or intrachip signal transfers. Signal transfer rates of greater than 2 gigabits/second (Gbps) per pin are achievable using standard CMOS technology and existing packages at a low cost. Designers can easily apply the technology to DRAM (memory bus), SRAMs (back-side bus), CPUs (front-side bus), network processors, ASICs, intrachip buses, and so on
