Abstract: The matrix uses a quantity of memory cells, along with a process for storing data in one quantity and a process for calling data from another quantity. The quantity of memory allows the functionality of a cell with repeated write connections by means of a quantity of cells with simple write connection and allows multiple simultaneous write accesses. The information, which is contained in the quantity of memory, is presented through all the memories together. It can be retrieved by a read function, which records on a subset of the named quantity. Stored data have three subsets A,B and C, operated on by read and write functions. Writing access is accomplished in three steps. First the contents of all memory, which are not modified, are read. As next values are calculated in a way, which are to be entered in a subset B of the named quantity of memory. The contents and the values of the subset B together represent the desired result. Device for reading contents of subset C of data uses data stored jointly.
