Methods of operating memory systems and memory systems are disclosed, such as a memory system having a memory array storing a code generating program to instruct a processor to generate a code, and a register to store a code generated by the processor, where the register is configured to allow a write operation to the memory array in response to a match of a code stored in the register and where the match is controlled in response to a request from a utility program being executed by the processor.

Flash device security method utilizing a check register

A method and system for using processor compatibility information to select a compatible processor for addition to a multiprocessor computer. A software program is executed on the multiprocessor computer to determine the number of current processors in the multiprocessor computer and the revision number of each processor. A software program that compares the revision numbers of the current processors with processor compatibility information is then executed to determine the revision numbers of processors that are compatible with all current processors.

Method and system for selecting compatible processors to add to a multiprocessor computer

A security method for preventing accidental or unauthorized writes to a flash memory. According to one embodiment of the present invention, a BIOS program stored in a flash memory array generates a random access code when executed by a processor. A check register stores the random access code and enables write operations to the flash memory array based upon an externally provided access code. In another embodiment, the BIOS program directs the processor to write the random access code to the check register to enable write operations in response to an external write request.
