Memory IC FAQ

How does the Quad Enable (QE) bit affect the HOLD function?

When the QE bit is set to 0, the HOLD function is available via the HOLD# pin. When QE is set to 1, the HOLD function is disabled, and the HOLD# pin acts as a dedicated data I/O pin (IO3).

What is the purpose of the Dummy Configuration (DC) bit?

The DC bit selects the number of dummy cycles between the end of the address and the start of read data output. This provides additional latency needed to complete initial read access before data can be returned, especially at higher frequencies like 104 MHz.
