Abstract
A word data loading circuit for a spatial light modulator includes a shadow load register (SLR), a load controller, and a word pattern generation (WPG) circuit. The SLR loads a first word of a pseudorandom image pattern. The load controller parallel shifts the first word to a memory cell array. The WPG circuit generates a next word and controls the SLR to change the first word to the next word. The load controller parallel shifts the next word to the array. The WPG circuit generates an additional word and controls the SLR to change the next word to the additional word. The load controller parallel shifts the additional word to the array. The WPG circuit, SLR, and load controller generate and parallel shift further additional words to the array until the pseudorandom image pattern is loaded in the array.
