An X16 nonvolatile memory has 16 input/output (I/O) ports, identified as I/O ports [15:0], and adopts a conversion method, which allows the memory to operate in an X16 mode or in an X8 mode. The method includes receiving a first user command that is sent by an upper computer and belongs to a user mode; determining a disabling command for a module path of the high-bit I/O ports [15:8] according to the first user command; and executing the disabling command and disabling the module path for controlling the high-bit I/O ports [15:8] of the memory so as to operate in an X8 mode.
