Abstract

The invention relates to a method for writing and reading digital information values in and out of the storage cells of a memory, said storage cells being organized in lines and columns. The information values are both written and read line by line and column by column in an alternating manner. A complete cycle of a writing and reading operation comprises the following steps. Starting from an initial cell of the memory, the information values are written line by line/column by column in the memory. After the information values are completely written line by line and column by column in the memory, the memory reads out in a line by line/column by column manner. The initial cell is displaced around a position within a line/column by inserting a column/line. All columns/lines of the memory are read out starting from the displaced initial cell.
