1325419 Transistor bi-stable INTERNATIONAL BUSINESS MACHINES CORP 3 July 1972 [29 July 1971] 31008/72 Heading H3T [Also in Division H1] In a monolithic data storage apparatus in which each bi-stable storage cell includes bipolar transistors and has associated accessing circuitry also including bipolar transistors, the current amplification of the storage transistor is lower than that of the accessing transistors. Preferably the storage and accessing transistors comprise respective halves of double-emitter transistors T1, T2, and the difference in current amplification is achieved by providing the two halves of each transistor with different base widths (see Division H1).
