1. A method for modifying memory, the method comprising: receiving a command including a user access key; using said user access key to determine whether said command is received via a customer-specific interface; ignoring said command when said command is not received via said customer-specific interface; permitting access to protected memory on a chip when said user access key matches a customer-specific access key stored within said chip and when it is determined that said user access key is received by said chip via said customer-specific interface; and when access to said protected memory is permitted, formatting information communicated to and/or from said protected memory during access of said protected memory based on one or more formatting criterion.
