Memory IC FAQ

How does the hardware write protection function operate?

Connecting the WP pin to VCC inhibits all write operations, protecting the entire memory array. Tying it to VSS enables normal read and write access.

What is the purpose of Acknowledge Polling?

It allows the master device to determine when an internal write cycle is complete by repeatedly sending a write command until the device acknowledges, thereby optimizing bus efficiency.
