responding to said received one or more of said plurality of read memory device ID commands by said one or more memory devices, wherein said response comprises identification information corresponding to said one or more memory devices and identifying one or more access protocols that are utilized to access said one or more memory devices.
13. The machine-readable storage according to claim 12 , wherein said one or more of said plurality of read memory device ID commands corresponds to one or more of a plurality of supported memory devices.
14. The machine-readable storage according to claim 13 , wherein said at least one code section comprises code for determining whether said response identifies said one or more memory devices as one of said one or more of said plurality of supported memory devices.
15. The machine-readable storage according to claim 14 , wherein said at least one code section comprises code for utilizing at least one access protocol for performing one or more of reading from said one or more memory devices, erasing said one or more memory devices, and writing to said one or more memory devices, if said response identifies said one or more memory devices as one of said one or more of said plurality of supported memory devices.
16. The machine-readable storage according to claim 14 , wherein said at least one code section comprises code for indicating an error condition, if said response does not identify said one or more memory devices as one of said one or more of said plurality of supported memory devices.
17. The machine-readable storage according to claim 13 , wherein said at least one code section comprises code for repeating said receiving and responding, if said one or more memory devices is not identified as one of said one or more of said plurality of supported memory devices.
18. The machine-readable storage according to claim 13 , wherein each of said received one or more of said plurality of read memory device ID commands is specific to a group of said one or more of said plurality of supported memory devices.
