Abstract
A method and/or system for checking the bus/interface between a host and a memory system during memory access operations includes a memory system having one or more of the data memory devices and a spare memory device; providing a bus/interface between a host and the memory system; selecting information on a per memory device basis to associate with a spare memory device; disassociating the selected information from the one or more data memory devices and associating the selected information with the spare memory device; adding Cyclical Redundancy Check (CRC) code to the one or more data memory devices from which the selected information was disassociated; transferring the CRC code and information over the bus and interface between the host and the memory system; and checking the bus interface with the CRC code added to the one or more data memory devices.
