Information storage device

Claim 1

AN INFORMATION STORAGE DEVICE COMPRISING A MATRIX OF MAGNETIC CORES CAPABLE OF ASSUMING BISTABLE STATES OF MAGNETIC REMANENCE, ARRANGED IN ROWS AND COLUMNS OF SAID MATRIX FOR SERIAL STORAGE OF BINARY INFORMATION IN RESPECTIVE ROWS, A COUNTING CHAIN COMPRISING A MAGNETIC CORE SHIFTING REGISTER CONNECTED UPON ITSELF, THE CORES OF SAID CHAIN EACH HAVING AN INPUT WINDING AND A SHIFTING WINDING, ALTERNATE CORES BEING PROVIDED WITH A SECOND OUTPUT WINDING, SAID SECOND OUTPUT WINDING BEING CONNECTED TO COLUMN LEADS OF SAID MATRIX, MEANS REVERSING THE MAGNETIZATION OF THE CORES OF THE SAID CHAIN AND PROVIDING PULSES THEREIN TO APPLY A READING IMPULSE IN EACH COLUMN IN ONE DIRECTION FOLLOWED BY A RESTORING IMPULSE IN THE OPPOSITE DIRECTION, SAID IMPULSES BEING OF INSUFFICIENT AMPLITUDE TO REVERSE THE MAGNETIZATION OF SAID CORES OF SAID MATRIX, AND MEANS FOR APPLYING ADDITIONAL IMPULSES TO SELECTED ONES OF THE ROWS OF SAID MATRIX WHICH WHEN COMBINED WITH SAID READING PULSES WILL BE SUFFICIENT TO REVERSE MAGNETIZATION IN SAID CORES OF SAID MATRIX, WHEREBY TO STORE SAID INFORMATION IN THE FORM OF MAGNETIZATION OF CORES ACCORDING TO THE SEQUENCE OF SAID ADDITIONAL IMPULSES.
