Abstract

PURPOSE: To improve reliability of write information, by erasing needless bubbles for write dependent upon a new creation type bubble generator immediately.
CONSTITUTION: The generator part of a new creation type magnetic bubble memory chip has conductor pattern 1a and bubble transfer pattern 1b. For write of "1", "0" is first written by erasing pulse Ann1, and bubble generating pulse Gen is flowed just after this write. For write of "0", only Ann1 is flowed, but Gen is not flowed. Further, Ann2 is flowed at the timing later than Gen and Ann1 by 200±20° for write of "1" to erase immediately generation of needless bubbles dependent upon Gen.
