Rows of magnetic cores 11 in a data store are arranged in pairs, each column winding 10 threading only one core in each pair of rows, and row windings 1, 2 are connected to different primary windings 15, 16 of a transformer 14, so that when partial select currents are supplied to row and column windings the secondary winding 17 of transformer 14 responds to the difference between the currents flowing through row windings 1, 2, any difference being indicative of switching of a core. Since diodes 12, 18, 19, 20 are forward biased by the partial select currents a pulse due to switching of a core can flow through line 1, winding 15, capacitor 21, winding 16 and line 2. Gate 3 is opened slightly before gate 9 to allow transients to settle.</p> |
