ABSTRACT:
A memory system is provided which comprises a main memory that stores main data and reference data; a first storage that stores the reference data; and a controller that accesses the reference data from the main memory upon receipt of a power up signal, and loads the main data into a second storage when the reference data retrieved from the main memory is tested to be the same as the reference data in the first storage. A method is also provided for booting a nonvolatile memory, comprising prestoring in a main memory a boot code and a reference data; prestoring the reference data in a register; accessing the reference data from the main memory when power is turned on; comparing the reference data in the register against the reference data accessed from the main memory; and loading the boot codes into a boot RAM if the reference data in the register is the same as the reference data accessed from the main memory and if not the same, repeating accessing and comparing the reference data from the main memory against the reference data in the register.
