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 mode utilizes IO0 and IO1 pins to transfer data at twice the rate, achieving up to 160Mbits/s.

How is write protection implemented in this device?

Write protection is achieved via software using Block Protect bits in the Status Register or via hardware by driving the WP# pin low to protect specific memory areas.
