摘要： Each memory cell of a memory device is connected to a bit line of a memory array and is associated with a read/rewrite amplifier connected between the bit line and a reference bit line. The bit line and the reference bit line are precharged to a predetermined precharge voltage. The content of a selected memory cell is read and refreshed based upon an associated read/rewrite amplifier. Between the precharging and the reading and refreshing, two capacitors previously charged to a charging voltage greater than the precharge voltage are respectively connected to the bit line and to the reference bit line.

摘要： At a charging phase, a capacitor (PC) is charged through two complementary charging transistors (TR1, TR2) connected in series to a first terminal (T1) of the capacitor (PC). At a voltage multiplication phase, an input voltage (Vdd) is delivered to the second terminal (T2) of the capacitor and an output voltage (Vout), increased with respect to the input voltage, is recovered at the first terminal (T1) of the, capacitor, and the capacitor is discharged during a discharging phase. During three phases, the substrate (BK2) of the charging transistor (TR2) directly connected to the first terminal (T1) of the capacitor is slaved to the source (S2) of this same charging transistor (TR2), while still keeping the source-substrate junction and the drain-substrate junction of this charging transistor (TR2) reverse-biased.

摘要： A memory read circuit includes an input to be connected to a bit line to which there are connected memory cells, and an output to produce an output logic potential. A current source produces a first current and a current-voltage converter produces the output logic potential. This potential represents the value of a second current obtained by the rerouting of a part of the first current towards the bit line when one of the cells is read, so that once the bit line is charged, the value of this second current is determined solely by the state of the selected cell and is independent of the equivalent capacitive load of the bit line.

摘要： A memory accessible in read mode only comprises storage elements designed to contain a bit that can assume two levels. Each memory cell comprises a transistor. The transistor of the storage element may include an associated circuit portion to prompt a short circuit between the drain and the source of the transistor if the storage element has to contain one bit at one of the two levels. Furthermore, the use of an unbalanced differential amplifier permits an improvement of the access time of the memory.

摘要： A frequency divider, constituted by N divide-by-two binaries, comprises logic circuits that enable the generation of a signal of the end of the frequency division by means of the change in state of the most significant bit generated by the Nth order divide-by-two binary. A binary code C representing a decimal integer value V is applied to the divider circuit. The frequency divider comprises circuits that enable the performance of a variable order division (V+1, V, . . . V-p, where p is a whole number greater than or equal to 1 and smaller than N-1) for one and the same binary code C.
