Abstract: A memory circuit for use with a spatial light modulator having an array of electrically addressable, micro-mechanical, modulating elements, whose address electrodes determine how that element will affect incident light. The memory circuit has at least one static memory cell in communication with the address electrodes of each modulating element. Each memory cell receives data for determining its micro-mechanical movement via a bit-line down each column of memory cells. A row select signal determines whether the data will be written to that row. A two-level voltage line supplies power to each memory cell, with one level being used for writing to the cell and another level being used for operating the modulating element.
