Memory IC FAQ

What is the difference between Standard SPI and Dual Output modes?

Standard SPI uses four signals (SCLK, CS#, SI, SO), while Dual Output utilizes IO0 and IO1 pins to transfer data at twice the rate, achieving up to 160 Mbits/s.

How is the status register protected?

Protection is managed via the SRP bit and WP# pin. Setting SRP to 1 and WP# to 0 locks the status register in hardware protected mode, preventing further writes.
