ABSTRACT:
Forming the shift register as a plurality of memory locations in a memory array where the input port for writing into the memory and the output port for reading out of the memory are sequenced along the array. Thus the input and output ports are shifted with respect to the array instead of the information shifting with respect to fixed input and output ports. The length or number stages of the shift register may be varied by changing the displacement or offset of the output or reading port to the input or writing port in the sequence.
