    Abstract: The method involves providing a ready/busy pad contact (RBP) in each sequential access memory. A contact management circuit (RBCT) and a central unit are provided in each memory to force the contact to a predetermined electrical potential. Execution of read or write command for integrated plane memory (MA) in each sequential memory is prevented when the contact presents the predetermined potential. An independent claim is also included for a sequential access memory comprising a serial input/output and an integrated plane memory.

    Abstract: The IC (1) has two memories (2,3) each controlled by a microprocessor (4,6). Each microcontroller has a circuit (13,14) executing the memory read or write operation. The read or write operations are carried out independent of the selected signal (SS1,SS2). A selection circuit (5) allows one of the memory circuits to be selected.

    Abstract: In a device for programming EPROM-Flash type memory cells of memory words of a memory, a bit line of a memory cell of a given rank of the first word and at least one bit line of a memory cell of the same rank in a word that is horizontally adjacent to this first word are connected together to two common programming connections by means of a bias circuit, and the bias circuit comprises two bias voltage inputs and one bias voltage output. The programming method consists in the successive programming, during different programming cycles, of the different cells of this first word and, during the same programming cycle, a different cell, of the same rank, in at least one word that is different from this first word is programmed.

    Abstract: The Multi-Level Memory has a matrix (1) of non volatile memory cells (1) memorising two bits of information. The matrix is divided into sectors which are addressable (3,4) and programmable (6,7,8). Read and Write circuits (5) are associated with the matrix. A real time clock (14) updates a command circuit (2) which periodically refreshes (2A) the memory cells.

    Abstract: The invention concerns an integrated circuit comprising a detection circuit (10) and a rectifier circuit (20) associated in series, to supply a rectified voltage (HV1, HV1), and a low voltage regulating circuit (30, 34) which receives the rectified voltage (HV1) and supplies a low voltage (Vcc). The invention is characterised in that the circuit further comprises a voltage producing circuit (100) which receives the rectified voltage (HV1) and produces high voltage (HT) different from the low voltage (Vcc). In one embodiment, the circuit also includes a memory (40) comprising a memory plane (42), the memory plane receiving the low voltage (Vcc) and the high voltage (HT).

    Abstract: L'invention concerne un procédé de programmation d'une cellule mémoire présentant une courbe de transconductance (C3) déterminée. La programmation de la cellule mémoire comprend une succession de cycles de programmation comprenant chacun une étape de vérification de l'état de la cellule mémoire. Selon l'invention, l'étape de vérification comprend une première lecture de la cellule mémoire avec une première tension de lecture (Vy1) supérieure à une tension de seuil de référence (VTref), et une seconde lecture de la cellule mémoire avec une seconde tension de lecture (Vy2) inférieure ou égale à la tension de seuil de référence (VTref). La cellule mémoire est considérée comme n'étant pas dans l'état programmé si des courants (I3, I3') de première et de seconde lecture traversant la cellule mémoire sont supérieurs à des seuils déterminés (Iref1, Iref2), et des impulsions de tension de programmation sont appliquées à la cellule mémoire tant que celle-ci n'est pas dans l'état programmé. Application notamment à la programmation de cellules mémoire Flash.
