Abstract
A memory cell for driving a complementary pair of electrodes associated with a micro-mirror of a spatial light modulator includes two PMOS transistors coupled to a voltage source providing a source voltage. The two PMOS transistors are characterized by a first size. The memory cell also includes two NMOS transistors coupled to ground. Each of the two NMOS transistors are coupled to one of the two PMOS transistors and are characterized by a second size substantially equal to the first size. The memory cell further includes two word line transistors coupled to a word line and characterized by a third size substantially equal to the first size. Power savings associated with the precharge circuit on the order of (Vdh/Vdl)=36 are achieved in some embodiments.
