Claim:
1. A write apparatus configured to perform a write operation for a magnetic memory that stores information using a magnetic domain, wherein the apparatus comprises: a first drive port; a second drive port; a first information storage area; a second information storage area; and an information buffer, wherein one end of the first drive port is connected to the first information storage area, wherein the other end of the first drive port is configured to connect to a power supply, wherein one end of the second drive port is connected to the second information storage area, wherein the other end of the second drive port is configured to connect to the power supply, wherein a first area locates between the first information storage area and the information buffer, wherein a second area locates between the second information storage area and the information buffer, wherein the first information storage area, the second information storage area, and the information buffer are made of a first magnetic material, wherein the first area and the second area are made of a second magnetic material, wherein the first magnetic material is different from the second magnetic material, wherein magnetic energy of the first magnetic material is higher than magnetic energy of the second magnetic material, wherein the first information storage area is configured to write first data to the information buffer when the first drive port is driven by the power supply, wherein the first data is represented by an electron set having a first spin direction, wherein the second information storage area is configured to write second data to the information buffer when the second drive port is driven by the power supply, wherein the second data is represented by an electron set having a second spin direction, wherein the first spin direction is reverse to the second spin direction, wherein the information buffer is configured to buffer data written from the first information storage area or the second information storage area, and wherein the buffered data is written to a magnetic domain of the magnetic memory.
