    摘要: The output buffer stage includes a half-bridge output stage having a first pair of complementary drivers connected in series between a supply line and a ground node, the high impedance state or conduction state of which is determined through a pair of control phases. The buffer stage includes a pair of switches controlled by the control phases, connected in series between them and connecting the transistors of the first stage in series. Each driver is connected in series with a switch, that is quickly opened to prevent under-threshold currents from circulating when the respective driver is turned off, and that is rapidly turned off when the respective driver is turned on.

    摘要: A sensing circuit for a semiconductor memory, includes, a detecting amplifier including a first circuital branch is run through by a first current corresponding to the sum of a second current as a function of a comparison current and a cell current. The cell current is a function of a state of a memory cell to be read in a predetermined biasing condition. A second circuital branch is coupled as a current mirror configuration with the first circuital branch. The second circuital branch is run through by a third current proportional to the first current. A third circuital branch coupled to the second branch sinks a fourth current as a function of the comparison current. A fourth circuital branch coupled to is run through by a residual current equal to the difference between the third and the fourth current. The residual current assumes different values depending on the fact that the cell current is lower, equal or higher than the comparison current. A residual current sensitive means generates an indication of the state of the memory cell as a function of a value of the residual current.

    摘要: Described herein is a reading circuit for a nonvolatile memory device, wherein the currents flowing through an array memory cell to be read, and a reference memory cell with known contents, are converted into an array voltage and, respectively, into a reference voltage, which are compared to determine the contents of the array memory cell. The method envisages reducing the electrical stress to which the reference memory cell is subjected during reading, by generating and holding a sample of the reference voltage, then deselecting the reference memory cell, and then continuing reading using the sample of the reference voltage.

    摘要: A method for simultaneously programming a pre-established number of memory cells includes setting an initial number of memory cells to be simultaneously programmed equal to the pre-established number, and subdividing the initial number of memory cells to be programmed into subsets of memory cells. A program operation for simultaneously programming all the memory cells of each subset of memory cells is executed by forcing a current through all the memory cells of each subset of memory cells. The current has a program voltage associated therewith. The program voltage is compared to a threshold voltage during execution of the program operation. The method further includes stopping execution of the program operation if the threshold voltage is surpassed, reducing the initial number of memory cells to be simultaneously programmed, and restarting from the subdividing.
