Abstract
In some embodiments, a method includes receiving, at a voltage distribution circuit, a power enable signal. In response to the power enable signal, the voltage distribution circuit may connect a word line driver circuit to a bit-cell voltage circuit such that an operating voltage is received at a bit-cell circuit before a word line signal form the word line driver circuit is received at the bit-cell circuit, where the operating voltage is provided by the bit-cell voltage circuit. The method may further include the bit-cell circuit providing the operating voltage along a bit line based on a data stored at the bit-cell circuit and based on the word line signal. In some embodiments, a static noise margin of one or more portions of the bit-cell circuit may be improved. Additionally, in some cases, a wakeup time of the bit-cell circuit may be ignored, resulting in a faster read operation.
