An integrated loop memory cell with miniaturized Josephson junction dimensions (approximately 5 x 5 $mu$$m$$sup 2$) and very high Josephson current density (30 kA/cm$sup 2$) was made in a 2 $mu$m minimum line width lead alloy. The storage currents are easily set up with coincident word and digit pulses. Nondestructive read-out, write, and half selection was successfully performed. The deduced current transfer time during write is below 80 ps. (auth)
