Abstract
A data storage circuit includes an array of memory cells; a logic processing circuit configured to carry out a logic operation having N binary data as operands stored in N input memory cells, with N≥2, the second input/output nodes of the input memory cells being linked by a common bit line, the logic processing circuit comprising: a transimpedance amplifier stage configured to supply an analogue read signal from the voltage of the common bit line; a comparator intended to compare the analogue read signal with a first adjustable reference voltage in order to generate a digital output signal corresponding to the result of the logic operation; a control unit configured to adjust the reference voltage to an amplitude selected from among N distinct predetermined amplitudes, depending on the type of logic operation.
