Title: Data stores
IPC: G11C11/416
Filed: 1970-06-01
Abstract: 1280924 Bi-stable circuits INTERNATIONAL BUSINESS MACHINES CORP 1 June 1970 [9 July 1969] 26254/70 Heading H3T [Also in Division G4] A bi-stable cell 10 is connected through common input lines 16, 18 to the emitters of respective transistors T6, T7 whose bases receive a write signal to set the bi-stable cell, or receive an appropriate bias during reading to connect the cell output to a sense amplifier 22 connected to the collectors of T6, T7. A row of cells in a matrix store has a common pair of lines 16, 18 for all cells. The cells are selected by word lines 12, 14 common to each column, which are taken positive by a signal at T4 base to short out R3 and raise 12, and by conduction of T5 (due to conduction of T4) which turns off T3 and raises 14. Thus power to the cell is increased, and emitters e 2 , e 3  cease to conduct while e 1 , e 4  become effective to conduct through emitter resistors R16, R17 of T6, T7. During reading, the emitters e 5 , e 6 , e 9 , e 10  of diode-connected multiemitter transistors D1, D2 are held positive and therefore non-conductive, and emitters e 7 , e 8  are held by R7, R8, R9 at a potential such that T6, T7 are conductive. The collector currents of T6, T7 then depend upon the current supplied to their resistors R16, R17 by the lines 16, 18, and the differential amplifier T10-T15 responds accordingly. During writing, diodes D3, D4 are turned on by a signal at 24 to isolate the differential amplifier; also T9 is turned on to raise emitters e 7 , e 8 , while e 6 , e 9  are again positive, so that potentials applied to B 1 , B 0  determine which of T6, T7 conducts more heavily and this sets the bi-stable via emitters e 1 , e 4  of T 1 , T 2 . When not reading or writing, the potential at 20 is low enough to make e 6 , e 9  conduct and turn off the transistors T6, T7.  The diode D1 emitter e 5 , is said to provide temperature compensation for T6 base-emitter junction.
