  Non-reciprocal charge transport in supercurrent diodes (SDs) polarized
growing interest in the last few years for its potential applications in
superconducting electronics (SCE). So far, SD effects have been reported in
complex hybrid superconductor/semiconductor structures or metallic systems
subject to moderate magnetic fields, thus showing a limited potentiality for
practical applications in SCE. Here, we report the design and the realization
of a monolithic SD by exploiting a Dayem bridge-based superconducting quantum
interference device (SQUID). Our structure allows reaching rectification
efficiencies ($\eta$) up to about 6%. Moreover, the absolute value and the
polarity of $\eta$ can be selected on demand by the modulation of an external
magnetic flux or by a gate voltage, thereby guaranteeing high versatility and
improved switching speed. Furthermore, our SD operates in a wide range of
temperatures up to about the 70% of the superconducting critical temperature of
the titanium film composing the interferometer. Our SD can find extended
applications in SCE by operating in synergy with widespread superconducting
technologies, such as nanocryotrons, rapid single flux quanta (RSFQs) and
memories.
