Patent ID: 7889586

Claim:
A circuit comprising: at least one memory cell to store data, said data corresponding to predetermined values of an electrical characteristic thereof, wherein said electrical characteristic values are affected by a variability with temperature according to a first variation law; and a voltage generator to generate a voltage to be supplied to the at least one memory cell for retrieving the data stored therein, the voltage generator including first means to cause the generated voltage to take a value in a set of target values including at least one target value, depending on an operation to be performed on the memory cell, wherein the voltage generator further includes second means for causing the value taken by the generated voltage to vary with temperature according to a prescribed second variation law, said second means including a compensation circuit element including a MOS-type variable-conductivity element having a threshold voltage exhibiting a variability with temperature corresponding to the variability of the memory cell to cause the variation of the value taken by the generated voltage.
