1. A spatial light modulator (SLM), comprising:

  • an array of pixel-generating elements, each pixel-generating element being individually addressable with data, said array of pixel-generating elements having an associated array of memory cells for storing said data;

    at least one bit-line associated with each column of said memory cells for delivering said data to said column of memory cells;

    a row of shift registers for receiving portions of rows of said data from an external source for delivery to said memory cells, said shift register row having a total number of shift registers that is less than the number of said memory cell columns;

    a number of latches, wherein each output line of said shift registers is connected to a subset of at least two of said number of latches, wherein each latch is in data communication with a different bit-line of said array;

    a row decoder for generating a write signal for selecting which row of said memory array is to receive each said row of data; and

    a write line in data communication with each row of said memory cells.
