enabling the host system to read boot-up firmware from the Flash memory
device.
The device reduces power consumption in the
standby mode
when it detects
specific voltage levels on CE# and RESET#, or when addresses have been stable
for a specified period of time.
The
Write Protect (WP#)
feature protects the first or last sector by asserting
a logic low on the WP#/ACC pin or WP# pin, depending on model number. The
protected sector will still be protected even during accelerated programming.
The
SecSi™ (Secured Silicon) Sector
provides a 128-word/256-byte area for
code or data that can be permanently protected. Once this sector is protected,
no further changes within the sector can occur.
Spansion MirrorBit flash technology combines years of Flash memory manufac-
turing experience to produce the highest levels of quality, reliability and cost
effectiveness. The device electrically erases all bits within a sector simultaneously
via hot-hole assisted erase. The data is programmed using hot electron injection.
