摘要： A dual-mode smart card comprising several pads of physical contact with an external reader and two pads of connection to an antenna for a contactless operation, and comprising a voltage regulator capable of extracting from a radio frequency excitation reaching the antenna, a supply voltage of the chip's processing circuits, this regulator being controllable by a central circuit to be deactivated in the presence of a supply voltage on contacts of the chip.

摘要： The invention relates to a memory cell with a binary value consisting of two parallel branches. Each of said branches comprises: at least one polycrystalline silicon programming resistor (Rp1, Rp2), which is connected between a first supply terminal (1) and a point or terminal for the differential reading (4, 6) of the memory cell state; and at least one first switch (MNP1, MNP2) which, during programming, connects one of said read terminals to a second supply terminal (2).
