Abstract
A random access memory element, fed by a constant current source, contains two complementary transistors forming a pnpn or npnp structure, with a lateral transistor and a transverse transistor. The constant current source is connected to an emitter of the lateral transistor, which is at a distance from its collector. This transistor has a second emitter near this collector, this second emitter receiving a control voltage which is able to trigger the assembly.
