Memory IC FAQ

What is the default state of the internal ECC feature?

The internal ECC is enabled by default (ECC_EN=1). Users can disable it if necessary, which changes the spare area organization.

How does the device handle power loss during operation?

Power should not be turned off before Write/Erase operations are complete to avoid data loss or damage. The device includes power lock down protection features.
