Abstract: First and second bit lines are arranged on one side of each sense amplifier while third and fourth bit lines are arranged on the other side thereof. A first dummy cell is connected to either the first bit line or the second bit line. In addition, a second dummy cell is connected to either the third bit line or the fourth bit line. When a memory cell connected to the first bit line is selected, the second dummy cell is simultaneously selected. On this occasion, the first bit line is connected to a first terminal of the sense amplifier, and the third bit line and the fourth bit line are connected to a second terminal of the sense amplifier. Potentials of the first and second terminals are differentially amplified. On the other hand, when a memory cell connected to the third bit line is selected, the first dummy cell is simultaneously selected.

Abstract: A method and device are provided for the transmission of data. After organizing the data into words all having the same number of bits, tables are formed each comprising a plurality of words, the words of these tables are coded by means of an error correcting code, and the bits of each table are transmitted using an interleaving method, at a transmission rate sufficient so that, during the time of formation of the table of rank N, a number R of tables, of rank N, N-1, N-2, . . . , N-R are transmitted. The reverse operations are carried out at reception. This method makes it possible to tolerate interruptions in transmission having a relatively long duration, without introducing too great a delay between the source and the user circuit.
