    Abstract: A method and apparatus for the programming and erasure of a memory cell made out of floating-gate transistors and to the circuit pertaining thereto is described. It can be applied especially to non-volatile electrically erasable and programmable memories, for example EEPROMs and flash EPROMs. A programming voltage or erasure voltage comprising a voltage shift equal in value to a reference voltage is produced, followed by a voltage ramp comprising a rising phase followed possibly by voltage plateau, this voltage ramp being shifted in voltage by the value of the reference voltage and being followed, in turn, by a voltage drop. The value of the voltage shift is fixed at an intermediate value that is lower than the value of a so-called tunnel voltage of the memory cell but greater than the supply voltage.

    Abstract: A device for the addressing of redundant elements of an integrated circuit memory is disclosed. This memory comprises an array of row memory elements and column memory elements, respectively addressable by row addresses and column addresses, and at least one group of fuses to store the address of a faulty element of the memory. Each fuse is associated with a row/column address pair. Through the blowing of certain fuses in the group after testing of a memory element, the address either of a column element, if the faulty element is a column element, or of a row element, if the faulty element is a row element, is stored. Only the row addresses are enabled when the stored address is that of a row element, and only the column addresses are enabled when the stored address is that of a column element, in order to address either a row redundant element or a column redundant element.

    Abstract: The present invention relates to a method for programming a memory cell having a determined transconductance curve. The programming of the memory cell comprises a series of programming cycles each comprising a step of verifying the state of the memory cell. According to the present invention, the verify step comprises a first read of the memory cell with a first read voltage greater than a reference threshold voltage, and a second read of the memory cell with a second read voltage lower than or equal to the reference threshold voltage. The memory cell is considered not to be in the programmed state if first- and second-read currents flowing through the memory cell are above determined thresholds, and programming voltage pulses are applied to the memory cell while the latter is not in the programmed state. Application in particular to the programming of Flash memory cells.

    Abstract: A circuit for activating page-write operations in a floating-gate memory includes a first and a second time lag circuit. A resetting signal resets a first time lag whenever a word is written in a buffer of the memory. The first time lag circuit provides a state bit indicating that the first time lag has ended or not ended. The second time lag circuit activates a second time lag at the end of the first time lag and the end of the second time lag activates the writing of the page in the memory. The invention also relates to a method of writing in memory that uses a first and a second time lag.
