Memory IC FAQ

What is the default address mode upon power-up?

The device defaults to 3-Byte address mode upon power-up, indicated by the ADS bit being 0.

How is the device reset using hardware signals?

Driving the RESET# pin low for a minimum period resets the device to standby mode and clears all volatile bits to their default power-on states.
