INTEGRATED CIRCUIT CHIP OF RADIOFREQUENCY IDENTIFIER Russian patent published in 2012 - IPC G06K19/00 G11C16/06 

FIELD: physics.

SUBSTANCE: device has a contact pad (1) lead connected to control gates of floating-gate MOS transistors of memory elements (13), with sources of diode-connected n-channels of transistors (9 and 10), a p-channel MOS transistor (4), whose drain is connected to the drain of the diode-connected n-channel transistor (5), whose source is connected to the drain of the transistor (13), with the input of a modulator (20) and with the drain of the diode-connected n-channel transistor (6), whose source and the gate of transistor (4) is connected to the positive supply bus (+Ep) (19). The leads of contact pads (2 and 3) are connected to a resonance antenna circuit. Lead (2) is connected to drains of transistors (7), (9), (11) and the gate of transistor (8), and lead (3) is connected to drains of transistors (8), (10), (12) and the gate of transistor (7). Drains of transistors (11 and 12) are connected to the positive supply bus (+Ep) (19). Sources of transistors (13) are connected to drains of address n-channel MOS transistors (14), whose sources are connected to drains of address n-channel MOS transistors (15), whose sources and drains of transistors (7) and (8) are connected to the earth bus (⊥) (18). Gates of transistors (14) and (15) are connected to outputs of row (16) and column (17) decoders, respectively.

EFFECT: smaller size of the integrated circuit chip of a radiofrequency identifier, as well as possibility of writing an individual code in a block of read-only memory elements.
