Abstract

PURPOSE: To secure a sufficient gate area without entailing the shortening of access time and the lowering of memory density by connecting successively provided minor loops to alternate independent major transfer lines.
CONSTITUTION: Many minor loops 26 and 27 are provided successively and then connected to major transfer lines 22 and 23. In information write operation, generators 20 and 21 are driven alternatively in accordance with a train of information and odd bits, for example, are generated by generator 20 and moved along transfer line 22. Similarly, even bits are moved along transfer line 23. At the point when the information train is arrayed on each transfer line, swap replicate gates 28 and 29 are put into operation to send information trains to loops 26 and 27. Further, the functions of gates 28 and 29 read and rewrite information.
