Methods and systems for accessing protected memory are disclosed. Aspects of one method may include enabling access to protected memory on a chip when a user access key for the chip matches a customer specific access key that is pre-programmed and stored in a one-time programmable memory within the chip. The protected memory in the chip may comprise non-volatile memory. Portions of the protected memory may be allocated for access by different users. Accordingly, each user may have a different user access key to access the portion of the protected memory allocated to that user. A user may use offset to objects when sending commands to access the protected memory. The object may indicate memory address and data size. This may allow a level of abstraction where a customer may not need to know specific addresses for the portion of the protected memory being accessed.

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; andwhen 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. 2. The method according to claim 1, wherein said protected memory in said chip comprises non-volatile memory. 3. The method according to claim 1, further comprising allocating a plurality of portions of said protected memory in said chip for access by different customers, wherein each of said plurality of portions of said memory on said chip is accessed via a different user access key. 4. The method according to claim 3, further comprising pre-programming at least one memory location in said plurality of portions of said protected memory. 5. The method according to claim 3, further comprising assigning a list of objects to each of said customers, wherein an object of said list of objects indicates an address to a portion of said protected memory. 6. The method according to claim 5, wherein said object in said list of objects further indicates a data size associated with said address to said portion of said protected memory. 7. The method according to claim 5, wherein said object in said list of objects is accessed via an offset with respect to another object in said list of objects. 8. A machine-readable storage having stored thereon, a computer program having at least one code section for modifying memory, the at least one code section being executable by a machine for causing the machine to: receive a command including a user access key;use said user access key to determine whether said command is received via a customer-specific interface;ignore said command when said command is not received via said customer-specific interface;permit access to protected memory on a chip when said user access key for said chip 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; andwhen access to said protected memory is permitted, format information communicated to and/or from said protected memory during access of said protected memory based on one or more formatting criterion. 9. The machine-readable storage according to claim 8, wherein said protected memory in said chip comprises non-volatile memory. 10. The machine-readable storage according to claim 8, wherein said at least one code section further causes the machine to allocate a plurality of portions of said protected memory in said chip for access by different users, wherein each of said plurality of portions of said memory on said chip is accessed via a different user access key. 11. The machine-readable storage according to claim 10, wherein said at least one code section further causes the machine to pre-program at least one memory location in said plurality of portions of said protected memory. 12. The machine-readable storage according to claim 10, wherein said at least one code section further causes the machine to assign a list of objects to each of said users, wherein an object of said list of objects indicates an address to a portion of said protected memory. 13. The machine-readable storage according to claim 12, wherein said object in said list of objects further indicates a data size associated with said address to said portion of said protected memory. 14. The machine-readable storage according to claim 12, wherein said object in said list of objects is accessed via an offset with respect to another object in said list of objects. 15. A system for modifying memory, the system comprising: one or more circuits in a chip that are configured to receive a command including a user access key, use said user access key to determine whether said command is received via a customer-specific interface, ignore said command when said command is not received via said customer-specific interface; permit access to protected memory on said chip when said user access key for said chip matches a customer-specific access key that is stored within said chip and when it is determined that said user access key is received by said chip via said customer-specific interface; andwhen access to said protected memory is permitted, said one or more circuits are configured to format information communicated to and/or from said protected memory during access of said protected memory based on one or more formatting criterion. 16. The system according to claim 15, wherein said protected memory in said chip comprises non-volatile memory. 17. The system according to claim 15, wherein a plurality of portions of said protected memory in said chip is allocated for access by different users, wherein each of said plurality of portions of said memory on said chip is accessed via a different user access key. 18. The system according to claim 17, wherein at least one memory location in said plurality of portions of said protected memory is pre-programmed. 19. The system according to claim 17, further comprising a customer object translator block that stores a list of objects for each of said users, wherein an object of said list of objects indicates an address to a portion of said protected memory. 20. The system according to claim 19, wherein said object in said list of objects further indicates a data size associated with said address to said portion of said protected memory. 21. The system according to claim 19, wherein said object in said list of objects is accessed via an offset with respect to another object in said list of objects.
