Memory IC FAQ

Is the Quad Enable (QE) bit configurable?

No, the QE bit is permanently set to 1 by default and cannot be changed, ensuring IO2 and IO3 pins are always enabled for Quad operations.

What is the typical standby current consumption?

The typical standby current is 11μA, while the deep power-down current is typically 0.2μA.

How many dummy cycles are supported for DTR Quad I/O Fast Read?

The DC1 and DC0 bits allow configuration of dummy cycles for DTR Quad I/O Fast Read (EDH command), supporting values such as 8 or 10 cycles depending on the clock frequency.
