Method and programming device for detecting an error in a memory

摘要

The invention relates to a programming method and device for detecting an error and inhibiting writing into a memory. The invention provides for the inclusion, in the standard programming method, of a checking step for interrupting the programming procedure and generating an error signal detecting the attempted overwriting of a "0" with a "1". The checking step of the inventive programming method provides for an initial comparison between the contents of a plurality of bits being programmed and a corresponding plurality of bits to be written in, the generation of an error signal upon detection of homolog pairs with a value of "one", and the interruption of the byte programming procedure to prevent a "1" from being written over a "0". <IMAGE>
