A system and method for a communication terminal to manage memory and maintain a current application version for multiple applications are provided. Different logic gates, built with the same building block as described in this invention, will have the same schematics of transistor connection and also the same physical layout so that they appear to be physically identical under optical or electron microscopy. Additionally provided are products for inhibiting the fading of color and increasing the intensity of color in color-treated keratinous fibers. The method further includes forming a drain region spaced apart from a second sidewall of the gate stack.
