Title: Sequentially switched memory.
Inventor: DICKEY DAVID VAIL
IPC: G11C8/04
Filed: 1967-06-08
Abstract: 1,157,422. Circuits employing bi-stable magnetic elements. LITTON INDUSTRIES Inc. 8 June, 1967 [14 June, 1966], No. 26616/67. Heading H3B. The word driving cores of a magnetic store are operated sequentially by means of a magnetic core shift register. The cores 16, 18, 20, 22 of the recirculating register 14 are first set to the " 0 " state and then a pulse is applied to winding 66 on core 16 which changes the state of this core to the " 1 " state. Since diode 32 is connected as shown in the advance winding 24 the pulse induced in the advance winding is blocked. A pulse from clock A passing through winding 62 linking core 16, 20 resets core 16 to its " 0 " state causing a pulse to be induced in advance winding 24 which passes through diode 32 and switches the next core 18 of the register to the " 1 " state and also driving core 40 which causes a word pulse to be transmitted along conductor 70 linking the cores of the first word of the storage matrix 10. The word pulse causes the contents of the word to be read out on sense lines 48, 50, 52. Diode 34 blocks any current flow in advance winding 26 when core 18 changes to the " 1 " state. A clock B pulse is then applied to conductor 64 which switches core 18 back to the " 0 " state causing a current pulse in advance winding 26 which switches cores 42, 20 to their " 1 " states resulting in word 2 to be read out. Similarly the next clock A pulse switches core 20 back to its " 0 " state and cores 44, 22 to their " 1 " state and the following clock B pulse causes core 22 to switch back to its " 0 " state and cores 46, 16 to switch to the " 1 " state. Word read pulses are thus passed along conductors 74, 76 sequentially. At the end of the cycle word driving cores 40, 42, 44, 46 are reset to their first remanent state by pulses applied to conductors 54, 56, 58, 60. During a write cycle enhancing or inhibit pulses may be applied to conductors 48, 50, 52. Two cores per bit may be used in the storage matrix.
