Memory IC FAQ

What is the function of the Secured Silicon Region?

It provides an extra 256-byte sector that can be permanently locked by the customer for storing secure data or code, which cannot be changed once locked.

How does the device handle erase operations during active reading?

The Erase Suspend/Erase Resume feature allows the user to pause an erase operation to read data from or program data to any non-selected sector, then resume the erase operation.
