Abstract:
An integrated cell for extracting a binary value based on a propagation of an edge of a triggering signal in two electric paths, comprising, across two voltage supply terminals, two parallel branches each comprising, in series:a resistor for differentiating the electric paths; a read transistor, a junction of the resistor and the read transistor of each branch defining an output terminal of the interated cell, and the gate of the read transistor of each branch being connected to the output terminal of the other branch; and a selection transistor, wherein the resistors are made of polysilicon and are sized to have identical nominal values and wherein the cell is associated with a circuit for reading an initial state of the cell and for stabilizing this state by causing a stable and irreversible decrease, in the cell read operating current range, of the resistance associated with the branch outputting a high state.
