Patent application title: NON-VOLATILE MEMORY, MEMORY CARD USING THE SAME, AND INFORMATION PROCESSING APPARATUS

摘要

A nonvolatile memory capable of nonvolatile software write protection in a memory card and an information processing apparatus using a nonvolatile memory without a write protect function and a system technology using the same. A flash memory card using a rewritable nonvolatile memory that does not have a nonvolatile software write protect function, is a flash memory card which collectively erases and writes flash memory and a reset IC that generates a power-on reset signal upon power-on, And a card controller for controlling the interface with the protection memory. In the flat memory, a protection saving register for writing an address of an area to be subjected to write protection is set in the review area, and a protection range is set in the system.
