发明名称 Row selection circuit for fast memory devices
摘要 The selection/deselection circuit is for non-volatile memory word lines having a decoding line connected between a supply voltage and ground, and including a series of decoding transistors of the same conductivity controlled by respective selection signals and at least a load transistor whose conductivity is opposite to the conductivity of the decoding transistors in series with the series of transistors and biased by a control voltage. The load transistor produces an activating or deactivating voltage of a memory word line, and a circuit for controlling the load transistor is provided. Such an auxiliary control circuit includes a sensing element in series with the decoding transistors and the load transistor for producing a sensing signal switching between a first value when only one memory line is actually selected and a second value when multiple memory word lines appear to be simultaneously selected. Also, an inverter receives the sensing signal and outputs a first signal. A high pass filter receives the first signal and produces a control transient voltage for transitorily bringing the load transistor to a state of full conduction when the sensing signal switches from the first value to the second value.
