后面的小节介绍了SRAM和DDR SDRAM接口的时序约束示例。 9.1.1 输入接口 有两种指定输入接口时序要求的方法: 以AC约束的形式指定DUA输入端的波形。 指定外部逻辑到输入的路径延迟。 指定输入端口的波形 考虑图9-1中所示的输入AC约束:输入CIN在时钟CLKP的上升沿之前4.3ns必须保持稳定,并且必须要保持稳定直到时钟上升沿...
该值表示的是,DDR内存模块中的同一个单元中,在最后一次有效的写操作和下一次读操作之间必须等待的时钟周期。 增加tWTR的值,可以让内容模块运行比其默认速度更快的速度下;减小tWTR的值,可以提高读性能,但会降低系统稳定性。 tWTR_S表示不同bank,tWTR_L表示相同bank 11、tREF - Refreshh Period tREF (Refreshh P...

For a short period of time, this is the second time that we are reviewing an ASUS Zen 2 laptop with a powerful 8-core Ryzen CPU and NVIDIA GeForce RTX 2060 Max-Q. The first one was the ASUS ROG Zephyrus G14 GA401 and we were pretty happy with its performance, build quality, and...
the essential hardware components such as processor, drive, hard disks, RAM, WIFI modules etc. can be accessed via maintenance flaps or removable floor trays. Furthermore the battery is replaceable if not stated differently. Of course, even after expiration of your warranty period, we...
