Overview

UltimateLowPowerTM


With UltimateLowPower technology, available only from NEC Electronics, you can expect dramatic reductions in power consumption for a wide range of applications, including mobile devices.

The steady reduction in threshold voltage (VTH) and gate-oxide thickness with each new technology node has reduced active power consumption but increased standby leakage. At 130 nm and below, standby leakage can become critical. NEC Electronics' UltimateLowPower technologies reduce both active power consumption and standby leakage.

Three UltimateLowPower Technologies

UltimateLowPower is a synergetic set of three innovative technologies. Comprising both new device structures and advanced circuit designs, these technologies work together to deliver dramatic reductions in power consumption.



The synergy between these innovative device structures and circuit designs is the key to UltimateLowPower. Body bias optimized design and monitor circuit technologies were introduced at the 65 nm node, and the 55 nm node features high-k gate insulator technology for the ultimate in low power consumption.

Application Optimizations

Different applications can employ these UltimateLowPower technologies to varying degrees, depending on the necessary power/performance tradeoffs (Figure 4). The UltimateLowPower technologies enable the right tradeoffs to suit every application, from mobile devices that require low standby power consumption to high-performance servers.
