ABSTRACT:
Apparatus for assembling binary data bits in parallel by groups in variable, selected locations in a shift register for subsequent serial readout. One or more shift registers are arranged in a matrix of rows and columns of storage cells and addressed along one coordinate while a plurality of data are applied in parallel along the orthogonal. Selector circuits are controlled to selectively shift a data word to enable the first bit in the word to be stored in any storage position within the addressed coordinate, with each remaining bit in the word stored in a correspondingly contiguous storage position in the matrix. Bit storage cells of the shift registers are of the set-reset latch type so that once set they cannot be changed by subsequent data bits until the entire array is reset. This enables the overwriting of successive data bytes.
