摘要： A reading circuit is provided for reading a memory cell. The reading circuit includes a reference current source, a memory cell biased between its first and second terminals at a predetermined voltage, comparison means for comparing a current flowing in the memory cell with the reference current, and a control gate voltage source coupled to a third terminal of the memory cell. The control gate voltage source includes a virgin memory cell that is biased between two terminals with a voltage of equal value to the biasing voltage of the memory cell. The control gate voltage source produces a control gate voltage at another terminal of the virgin memory cell. In one preferred embodiment, the memory cell and the virgin memory cell are EEPROM cells.

摘要： A biasing circuit may include an input configured to receive a supply voltage, a value of which is higher than a limit voltage. The biasing circuit may also include a control stage configured to generate first and second control signals with mutually complementary values, equal alternatively to a first value, in a first half-period of a clock signal, or to a second value, in a second half-period of the clock signal. The first and second values may be a function of the supply and limit voltages. The biasing circuit may also include a biasing stage configured to generate a biasing voltage as a function of the values of the first and second control signals. The first and second control signals may control transfer transistors for transferring the supply voltage to respective outputs, while the biasing voltage may be for controlling protection transistors to reduce overvoltages on the transfer transistors.
