Leakage Current Mechanisms and Estimation in Memories and Logic 249
are treated separately. More details on system level memory leakage reduction
can be found in this chapter, and circuit level techniques to reduce memory
leakage can be found in the next chapter. However, logic leakage is also crucial;
the treatment of logic is treated later in this chapter.
7.3.2 Use of G versus LP technology
The actual energy lost in leakage depends on how long the core is active and
how much the leakage power is. The first part depends on the application
profile; however, the leakage power depends on the choice of technology.
Most fabs provide two broad technology fla ...
