Abstract

PURPOSE: To control the elements different in memory capacity at the same way, by providing the circuit in which the timing operating the transfer gate and sensor of the magnetic bubble memory element is directly given to element and is done delayed by a suitable time.
CONSTITUTION: When the samll capacity bubble memory element is connected to the distrubition circuit 57, the selector switch 568 is at ON state. When the output 03 of the address conversion 51 is 1, the transfer timing TRF signal T and the sensor timing S are fed to the memory element 581 as they are. If the output 03 is zero, desired timing is appeared only at the element 582. Next, the switch 568 is opened and it connects the large capacity element. When the output 03 is 1, TRFTo and the sensor timing So are fed to the element 581 or the element 582, and TRTFT1 and the sensor timing S1 are fed to the element 582 or 581. In this case, since the signal T1 and S1 are delayed by a given time with the delay circuits 562 and 564, access time can be made equal even with large capacity and also small capactity.
