Memory IC FAQ

How does the Dual SPI interface improve performance?

Dual SPI allows data to be transferred at two times the rate of standard SPI by using both SI and SO pins as bidirectional I/O lines during read operations.

What is the purpose of the Unique ID Number instruction?

It accesses a factory-set 64-bit number unique to each device, which can be used to prevent copying or cloning of the system.
