These is a 1Gb NOR FLASH with 2 die structure(MT25TL01GBBB8ESF-0AAT).

It request 8 IOs so that I connect both BK1 and BK2 of H7 MCU.

Depend on the dual-die configuration involved. The STM32H747I-DISCO provides connectivity to pin 6 and 13, and foot-prints to place one or two IC

The series resistors are there to suppress the ringing/reflections on short traces at high rates
