Abstract

A storage module (1) and an access module (2) are interconnected by data and control signal lines (3). The register block (6) of the storage module comprises N value registers (W1-WN) each contg. n binary storage cells (E1-En). These are nonvolatile and any failure or removal of the power supply results in no loss of data from either the register block cells or those (M2-MN) of the mark register (7). Data can be shifted to the next higher register (e.g. W2) where the state of a particular cell and the associated bit of the mark register are inverted in uninterruptable execution steps. <IMAGE>
