Abstract
A data storage circuit includes a matrix of memory cells such that each memory cell comprises: a read circuit associated with at least one memory cell, comprising: a capacitive transimpedance amplifier stage configured to read a datum stored in a memory cell; the capacitive transimpedance amplifier stage comprising: an operational amplifier; a feedback capacitive impedance mounted between the output and the first input of the operational amplifier; a sequencer circuit configured to, following the reading of a datum corresponding to the second logic state, apply a control signal to the first input/output node having an amplitude lower than the first reference signal and maintain the selection transistor in an on state so as to replace, in the selected elementary storage component, a level of charges corresponding to the second logic state.
