Japanese Patent JPH0828114

B2

PURPOSE:To raise the stability of storage information, and to execute a high density storage by providing a means for writing a fluxoid quantum by a pre scribed number, and a means for reading out the number of fluxoid quanta which are written, in a hole formed in a superconductor thin film. CONSTITUTION:In order to trap a fluxoid quantum to a hole 2 of a designated address, a pulse of a current is sent to a Y-line and an X-line connected to a heating element placed in this hole. For instance, when a pulse current is applied simultaneously to a Y0-line and an X0-line, a superconductor 1 in the periphery of the hole existing in an intersection of both the lines becomes a normal conductor, and by applying a magnetic field having an intensity, which can confine a prescribed number of fluxoid quanta in the hole formed in the part transferred to the normal conductor, a signal corresponding to a prescribed data pattern can be written to an arbitrary coordinate of a matrix. At the time of reading it out, a pulse current is applied to a voltage applied line Y0 of a Hall element. When a signal is outputted to a Hall voltage detecting line X0 in accordance with this variation, moreover, when the amplitude of a Hall voltage is detected, it corresponds to the number of fluxoid quanta which are trapped, therefore, the contents of prescribed information can be known.
