Tiny graphene pores for sensors In fundamental work that will likely guide current and future graphene membrane design principles in years to come, MIT researchers have created tiny pores in single sheets of graphene that have an array of preferences and characteristics similar to those of ion channels in living cells, and which could be useful as sensors. The researchers pointed out that e... » read more

Higher Frequencies Mean More Memory

As SoCs get more complex, whether due to higher frequencies or adding more functionality, there is a spillover effect on bandwidth, [getkc id="22" kc_name="memory"] and power. There is no simple way to just turn up the clock frequency in a complex [getkc id="81" kc_name="SoC"]. That relatively straightforward objective will likely require more power domains, more cores, more ways to move sig... » read more

The Rise Of Layout-Dependent Effects

By Ann Steffora Mutschler Designing for today’s advanced semiconductor manufacturing process nodes brings area, speed, power and other benefits but also new performance challenges as a result of the pure physics of running current through tiny wires. Layout-dependent effects (LDE), which emerged at 40nm and are having a larger impact at 28 and 20nm, introduce variability to circuit ... » read more
