Cpu bus buffer

Webthe processor’s data bus. Because of this, the capacitive loading presented by each bank to the memory array’s data bus is usually much less than that presented to the memory array’s address bus. This loading difference allows adata bus buffer to drive more memory banks than an address bus equivalent. This fact http://gauss.ececs.uc.edu/Courses/c4029/lectures/dma.pdf
