  • Pipelined error detection and correction apparatus with programmable address trap
    Patent number: 4905242
    Abstract: An error detection and correction apparatus utilizing seven internally generated check bits which are applied to incoming data signals on the next clock. The combination data signals are written into the system random access memory and are reapplied to the error detection and correction apparatus. An address trap register is programmed to trap the address of the single or multiple bit errors. The address trap register also captures the error flags and the syndrome bit so that detected faults can be isolated. A single bit error correction circuit is utilized to correct single bit errors in the data signal.
