Abstract:
A system and method for providing a memory device having a shared error feedback pin. The system includes a memory device having a data interface configured to receive data bits and CRC bits, CRC receiving circuitry, CRC creation circuitry, a memory device pad, and driver circuitry. The CRC receiving circuitry utilizes a CRC equation for the detection of errors in one or more of the received data and the received CRC bits. The CRC creation circuitry utilizes the CRC equation for the creation of CRC bits consistent with data to be transmitted to a separate device bits. The memory device pad is configured for reporting of any errors detected in the received data and the received CRC bits. The driver circuitry is connected to the memory device pad and merged with one or more other driver circuitries resident on one or more other memory devices into an error reporting line.
