DDRII SDRAM Memory Controller Interface Design and Application Based on Virtex-5 FPGADDRIIControllerIP coreChipScope proFor the currently the most widely used data storage memory is DDRII SDRAM which is used in the high-speed, high-precision, and high-memory depth of the data storage and ...
既然一个 Rank 就相当于一个大芯片,那么,要不要从 DRAM Controller 引出 CS 信号都无所谓了,只需在芯片端让 CS 引脚一直有效即可。 通常情况下,在嵌入式产品应用中,一个 Rank 就足以满足大部分产品的容量需求了。以 DDR4 为例,美光就有 4 位带宽高达 16Gb 容量的芯片(如 MT40A4G4),假如某 MPU 的内存...

DDR Memory Comparison (Source: synopsys.com) When choosing our memory type, we also need to watch out for the speed grade of the memory device and the speed rating of the memory controller within the FPGA. We can choose to ‘derate’ our memory or controller, thus not running at full ba...
