Abstract: PROBLEM TO BE SOLVED: To provide a multi-purpose memory device suitable for an application example of a wider range independently of whether reading of data is required or not in the asynchronous mode (as in standard memory) in random access or in a synchronous progressive mode in burst type access. SOLUTION: A memory device recognizes modes of access and reading required by a microprocessor, also enables performing self-conditioning of its internal circuit based on such a recognition to perform reading data in a required mode. At the time, an additional external control signal is not required, and sacrifice is not forced in an access time and a reading time as compared with obtained one in the case of a memory device constituted specifically for any one of operation modes for constitution of the same manufacturing technology and conventional technology.

Abstract: A redundancy architecture for a memory wherein the array of memory cells is divided in at least a pair of banks or semiarrays (EVEN_BANK, ODD_BANK) singularly addressable (ADDR_latch_E, ADDR_latch_O), organized in rows and columns; the architecture comprising a certain number of packets each composed of a certain number of redundancy columns of cells (REDUNDANCY), contemplates dividing said number of packets (REDUNDANCY) in two subsets of packets (REDUNDANCY_EVEN, REDUNDANCY_ODD), each one addressable independently from the other by way of respective address circuits and providing redundancy columns of cells exclusively for a respective bank or semiarray (EVEN_BANK, ODD_BANK).

Abstract: A new multipurpose interlaced memory device functions in two different modes: synchronous and asynchronous, using a circuit for detecting address transitions that by acting as a synchronous clock of the system lets the control circuit of the memory device recognize the required access mode by enabling a comparison of the currently input external address with the one stored in the address counters of the two banks of cells. The memory device has a buffer for outputting a datum provided with means that for pre-charging the output nodes to an intermediate voltage between the voltages corresponding to the two possible logic states, thus reducing noise and improving transfer time.

Abstract: Dans le procédé de gestion de données (300) pour une mémoire non volatile programmable bit à bit, le stockage de nouvelles données (NewDat) en un emplacement mémoire (Loc) d’un mot-mémoire comprend : - une étape de mesure (302) qui mesure les données précédentes (FormDat) stockées dans l’emplacement mémoire ; - le calcul (303) d’une première et d’une deuxième quantification (Q1, Q2) des opérations de programmation bit à bit correspondant aux bits des nouvelles données (NewDat), et d’une inversion complémentaire des nouvelles données (Compl.NewDat), qui sont respectivement différents des bits des données précédentes (FormDat), - une étape de programmation (306) comprenant, si la première quantification (Q1) est strictement supérieure à la deuxième quantification (Q2), la programmation bit à bit des bits de l’inversion complémentaire (305) des nouvelles données (Compl.NewDat) respectivement différents des bits des données précédentes (FormDat), et la programmation d’un drapeau d’inversion (InvFlg) à une valeur marquée.
