ABSTRACT:
A memory array having improved cross coupled cells arranged in rows and columns and provided with means that permit the speedy direct transfer of data from one cell in the array into another cell in the array while simultaneously reading the data. Each of the cells is provided with a pair of read transistors and is coupled between a pair of bit sense lines. A different pair of bit sense lines is associated with each column of cells. Each cell is, in turn, provided with a pair of write transistors and is coupled between a pair of write lines. A different pair of write lines is associated with each column of cells in parallel to the bit sense lines. Read and write decodes are coupled to rows of cells arranged orthogonal to the columns of cells. Means are provided for coupling the bit line data of the cell being read to the write lines of another cell in the array so as to transfer directly the information read from the first cell in one row of cells into a second cell in a different row of cells while simultaneously reading the information being transferred.
