This document describes the implementation of the advanced sector protection in Spansion flash memory devices.

Advanced sector protection offers designers multiple levels of sector protection to satisfy a variety of security and design needs. It protects the memory from erroneous codes, accidentally corrupting vital code and data. It also prevents hackers from corrupting the network by programming malicious viruses into the memory.

Advanced sector protection features several levels of sector protection. The scheme is divided into two parts. The persistent sector protection method replaces the 12 V, or VID, applied on the RESET# pin to initiate sector protect and unprotect. The password sector protection method is a one-time programmable scheme where a 64-bit password has to be entered for any subsequent programming of a sector. Spansion flash memory devices also have other types of sector protection such as SecSi sector, WP# pin and Standard Security.
