Abstract:
A method for reading a dynamic memory comprising at least one bit line, at least one word line, at least one storage cell accessible by the bit line and the word line, and at least one reference line, the storage cell enabling the storage of an initial potential representing a logic information element, the method comprising the steps of:precharging the bit line and the reference line to change potentials thereof to a level of a reference potential that is different from the initial potential stored in the storage cell;selecting the storage cell to produce a change of the potential of the bit line and thus create an initial difference between the potentials of the bit line and the reference line;discharging the bit line and the reference line so that the bit and reference lines are then crossed by discharge currents; andproducing an output signal having a state representing values of the discharge currents.
