Abstract: A circuit that includes a current source module, a current sink module and a memory bank is disclosed. Each of the current source module, the current sink module and the memory bank is connected to the first bit/source line and the second bit/source line. The memory bank is bounded by the current source module and the current sink module. When the current source module and the current sink module receive a triggering pulse from the first bit/source line and a select signal with a first state, the current source module is activated to generate an operating current to the first bit/source line that transmits through a conducted memory cell of the memory bank and the current sink module is activated to drain the operating current from the second bit/source line.

Abstract: A word line driver circuit includes a first transistor having its gate coupled to a first node configured to receive a word line select signal. A second transistor has its gate coupled to the first node and a drain coupled to a drain of the first transistor at a second node that is coupled to a word line. A word line assist control circuit is coupled to the first node, to the word line, and to a gate of a third transistor. The word line assist control circuit is configured to turn on or turn off the third transistor to adjust a voltage of the word line.
