Abstract
A memory cell for driving a complementary pair of electrodes associated with a micro-mirror of a spatial light modulator. The memory cell includes a first PMOS transistor, wherein a source of the first PMOS transistor is coupled to a first supply voltage. The memory cell also includes a first NMOS transistor, wherein a drain of the first NMOS transistor is coupled to a drain of the first PMOS transistor, a source of the first NMOS transistor is coupled to a second supply voltage, and a gate of the first NMOS transistor is coupled to a gate of the first PMOS transistor. The memory cell further includes a second transistor adapted to establish a conduction path between the gate of the first NMOS transistor and at least one of the first supply voltage or the second supply voltage. Moreover, the memory includes a select transistor, wherein a drain of the select transistor is coupled to the gate of the first NMOS transistor and wherein the memory cell is free from a connection to a fifth transistor.
