Memory IC FAQ

How does the Quad Enable bit affect pin functionality?

When the Quad Enable bit is set to 1, the WP# and HOLD# pins function as bidirectional I/O pins IO2 and IO3 to support Quad SPI operations.

What mechanism prevents unintended writes to the memory array?

The device uses a Write Enable Latch that must be explicitly set via command before any program or erase operation can occur, preventing accidental modifications.
