Abstract
A memory system providing capability for correction of multiple bit errors. The storage elements of the memory system are divided into four-bit nibbles, wherein storage of a single 32-word requires access to eight separate storage elements. A ninth storage element stores a four-bit error syndrome. All nine storage elements have single bit error correction/multiple bit error detection. All single bit errors are corrected directly within the individual storage element. Multiple bit errors within a single storage element are signaled to the interface controller which corrects the error using the stored four-bit error syndrome.
