Abstract

PURPOSE:To shorten the total access time by equalizing the distance between the farthest minor loop from a detector or generator and the detector or generator to the length of the minor loop or by increasing the distance to the generator one and half time the minor loop length. CONSTITUTION:Length lM from the closest memory position 18 to replicate gate 13-N in minor loop 11-N to detector 14 is equalized to minor loop length lm. In addition, length l'M from generator 17 to the closest memory position 19 to swap gate 16-1 in minor loop 11-1 is equalized to or increased one and half time lm. When said lengths lm and lM are equal to each other and addresses of pieces of information to be read in the following period are given as binary numerals at some time in order, the time of movement in the minor loop in access time is greatly shortened. When l'M is equal to or one and half time lm, the same result with regard to writing operation is obtained. Thus, the total access time can be shortened.
