A drive for a domain memory device contains a magneto-uniaxial film 1 with a SCHSCH 2, on the surface of which the information storage registers 3 are located, connected through the appropriate switch replicators of the CMD of the first 4 and second 5 groups and the corresponding information output registers of the first 6 and second 7 groups, respectively with the first 8 and second 9 CMD read elements the first group of 10 CMD generators 10, interconnected by a generation generation conductor 11 and connected through the information input registers 12 of the first group with the same name third storage registers 3, information entry registers of the second group 13, the central dialing switches 14 and the second 15, the second 16, the third 17 and the fourth 18 groups of the central dial generators, the replicators switches 4 and 5 of the central dialing magnetically connected by the output bus 19, and the switches 14 and 15 of the CMD are interconnected by the input bus 20. The numbers 21 and 22 indicate the positions occupied by the CMD during operation of the accumulator.

The drive works as follows.

groups 12 with the same information storage registers 3, information input registers of the second group 13, CMD switches of the first 14 and second 15 groups, the second 16, third 17 and fourth 18 groups of CMD generators. The switch replicators of the CMD groups 4 and 5 are magnetically connected to the output terminal 19, and the switches of the centers of the groups 14 and 15 are interconnected by the input bus 20. The numbers 21 and 22 denote the positions occupied by the CMD during operation of the accumulator, 1 sludge,

In the recording mode, the write current busbar 11 generates the write current pulses with a frequency equal to twice the control field E, when the vector control field H is in the position I of the CMD of the recorded information block is fixed on the magnetically soft application of the generators 10 CMD. the recorded bits are shifted in parallel in the information input registers 12. In the second half of each period of change of the control field (the vector H in position III), the next write current pulse is supplied, by paralleling the input of the CMD from the generators 16 of the CMD to the input registers 13. It should be noted that at the time of the onset of CMD in CMD generators 10 and 16, similar information is generated by CMD generators 18 and 17. However, if information from generators 10 and 16 of the CD is entered into input registers 12 and 13, respectively, information from CMD generators 18 and 17 is output via output registers 7 and 6, respectively, to elements 9 and 8 of the CMD readout. Thus, during each clock cycle of the control field, parallel input of both groups of two successive bits of the recorded information blocks into the input registers is carried out. Similarly, the remaining bits of the recorded information blocks are entered with a simultaneous shift of the previously recorded bits in the input registers through the switches 14 and 15 of the input to the registers 7 and 6 of the output information. At the same time, due to the fact that the width of each i-ro input register is greater than the size of the corresponding i-1 input register by one bit after K cycles from the start of information generation (K. is the number of storage registers in the drive) the switches of the first group arrive 1, 2, ..., To the bit of the first information block, and in the second half of the same clock cycle, 1.2, ..., K bits of the second information block are fed to the inputs of the switches of the second group. To enter the first information block into the storage registers, the input current bus 20 is supplied with an input current pulse when the vector CC is in position I. The first information block from the positions 21 of the switches of the first group is entered in parallel into the 1.2, ..., K registers stored information. In the second half-cycle of the K-th cycle (the vector H, is in position III) in a similar way

Cut switches 15 CMD in K, K-

-, ..., storage registers are entered 1,2, .., To the bits of the second information block. All the domains remaining in the information input registers are transferred to the registers of the second and first groups via the CMD switches of the first and second groups. and further, through the readout elements, the CMD are output outside the working area of the storage device

In the destructive read mode, the output first and second information blocks are fed to the input of switch replicators at position 22. At this time, a pulse of output current is applied to the output bus 19, with the result that the first information block simultaneously enters the first output register and then to the first element 8 read CMD. After half a cycle (the vector H is in position III), the bits of the second read block arrive at position 22 of the switches-replicators of the second group. The supply of a current pulse to the bus 19 causes a parallel output of the block bits to the output registers of the second group and further to the second read element of the CMD. Due to the fact that the width of each i-ro output register is one bit smaller than the corresponding (il) -x output registers, the bits of the read blocks are successively fed to the first and second read elements with a half clock shift of the control field Well, those. during each clock cycle, the like bits of the first and second readable information blocks are output.

(The output of information in the non-destructive read mode is similar to the reviewed destructive read mode and is characterized by the presence of a copy operation of the output bits of the first and second information blocks at the moments when the H in the vector

5 positions II and IV, respectively. For this, replication pulses are sent to the bus 19 at appropriate times. Thus in each step of the device can be

0, input or output of two bits of information has been performed, which doubles the speed of information exchange in the drive.
