Abstract
The invention relates to a system and method for controlling implementation of a command to a NAND memory device. The method comprises: monitoring an input/output (I/O) bus connected to the NAND memory device for an assertion of a write command for the NAND memory device. Upon detection of the write command, the method evaluates a destination address associated with the write command. If the destination address is not a restricted address for the NAND memory device, then the method allows the write command to modify the contents; and if the destination address is a restricted address for the NAND memory device, then the method prevents assertion of the write command on the contents.
