Some example embodiments presented herein provide methods and memory modules for configuring vendor-specific registers in the memory modules to enable and/or disable vendor-specific functionality. The vendor-specific register space may be organized by a vendor-specific logic and accessed by a standard memory access command received while the memory is in a programming mode. A write command may be received from a host device to switch the memory module to a programming mode, and the memory module may be switched to the programming mode responsive to the command. A memory write command may be received from the host device involving the memory module switched to the programming mode, and a vendor-specific register may be configured based on the memory write command and the organization of the vendor-specific register indicated by the vendor-specific logic.
