IPC: G11C7/02
Filed: 1965-07-28
Abstract: 1,052,737. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 28, 1965, No.-32191/65. Heading G4A. A read-only store having transformer cores selectively threaded by drive windings to store data, each core having a respective output winding connected to a sense circuit responsive to only one signal polarity, further comprises a compensating winding threading all the cores and carrying a current generated from the drive pulse so that spurious signals are eliminated or made of the polarity to which the sense circuits are not responsive. The compensating current is the differential of the drive current and can be obtained by connecting the compensating winding to the drive windings through a capacitor, or by making the compensating winding a closed resistive loop. The spurious signal produced from a core not threaded by the energized drive winding is normally first of one polarity and later of the other polarity and the above arrangements will not work for exceptional stored data patterns giving the polarities reversed. This can be solved by strobing off one end of the output signals or by obtaining the compensating current via a full-wave rectifier (diodes or transistors) from a differentiating transformer connected to the drive windings.
