Abstract

The present invention provides a various methods, systems and devices for controlling light modulating elements and/or spatial light modulators. In some embodiments of the present invention, a recursive feedback method is used to control light modulating elements and/or spatial light modulators.

Claims

1-160. -160. (canceled)

161. A device comprising:

a MRAM array of MRAM storage bits for a spatial light modulator, said MRAM storage bits being arranged in MRAM columns; and

one or more bit lines for each of said MRAM columns, wherein said one or more bit lines support a first and a second driver on opposite sides of said array, wherein said MRAM storage bits are for a spatial light modulator.

162. The device of claim 161, further comprising said first driver and said second driver.

163. The device of claim 162, wherein said first driver and said second driver each include means for masked writing to said MRAM storage bits.

164. The device of claim 161, further comprising a first processing means and a second processing means for writing to said MRAM storage bits, wherein said first processing means and said second processing means are located on opposite sides of said MRAM array and wherein either said first processing means or said second processing means is capable of writing to said MRAM storage bits on either side of said MRAM array.

165. The device of claim 161, further comprising ERAM storage bits interposed between said MRAM storage bits of said MRAM array.

166. The device of claim 165, wherein said ERAM storage bits is arranged in ERAM columns, wherein said ERAM columns form two separate ERAM memory arrays, and wherein each of said ERAM memory arrays includes inputs and outputs on opposite sides thereof.

167. A device comprising:

an array of drive bits; and

means for performing a masked write to said drive bits.

168. The device of claim 167, wherein said drive bits are part of a spatial light modulator.
