The
Erase Suspend/Erase Resume
feature enables the user to put erase on hold for any period
of time to read data from, or program data to, any sector that is not selected for erasure. True
background erase can thus be achieved.
The
hardware RESET# pin
terminates any operation in progress and resets the internal state
machine to reading array data. The RESET# pin may be tied to the system reset circuitry. A sys-
tem reset would thus also reset the device, enabling the system microprocessor to read the
boot-up firmware from the Flash memory.
The device offers two power-saving features. When addresses have been stable for a specified
amount of time, the device enters the
automatic sleep mode.
The system can also place the
device into the
standby mode.
Power consumption is greatly reduced in both these modes.
The Spansion Flash technology combines years of Flash memory manufacturing experience to
produce the highest levels of quality, reliability and cost effectiveness. The device electrically
erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The data is
programmed using hot electron injection.
