<p>Error detecting and correcting system which is simple, inexpensive and low in demands on memory capacity and memory cycle time. A memory for storing data includes a first section, the data being stored in the first section in rows and columns and first means for storing first check bits for the rows of data. Error correcting means (22) includes: means for generating check bits (62) for the columns of data so as to produce a check word for a predetermined number of the rows of data; a second memory section (26-3) for storing at least one check word; and processor means operatively coupling the generating means with said first and second sections to enable the error correcting means to utilize the first check bits to locate a row of data in which at least one bit is in error and also to enable the error correcting means to utilize the associated check word to correct any errors which exist in the row of data.</p> |
