Abstract:
1. A magnetic shift register, comprising: at least a magnetic memory track, having a plurality of magnetic domains to serve as a plurality of magnetic bit memory cells, wherein the magnetic memory track comprises: a plurality of data regions, wherein each of the data regions has a plurality of the magnetic bit memory cells for respectively storing a plurality of bit data at a quiescent state and registering at least one of the bit data directly shifted from an adjacent data region at a shifting state; a reading circuit, disposed at a reading position of each of the data regions for reading a bit data of the magnetic bit memory cell shifted to the reading position; and a writing circuit, disposed at a writing position of each of the data regions for writing a bit data into the magnetic bit memory cell shifted to the writing position, wherein the bit data of the magnetic bit memory cells is directly shifted between two adjacent data regions under an operation current.
