Patent ID: 7764535

Claim:
A memory cell for driving a complementary pair of electrodes associated with a micro-mirror of a spatial light modulator, the memory cell comprising: two PMOS transistors coupled to a voltage source providing a source voltage, wherein the two PMOS transistors are characterized by a first size; two NMOS transistors coupled to ground, each of the two NMOS transistors being coupled to one of the two PMOS transistors and characterized by a second size substantially equal to the first size; two word line transistors coupled to a word line and characterized by a third size substantially equal to the first size; a word line driver coupled to the word line; a multiplexer coupled to the word line driver; and a voltage supply coupled to the multiplexer and including a read voltage source providing a read voltage and a write voltage source providing a write voltage, wherein read voltage is less than the write voltage.
