摘要

An access method for a DRAM is provided. A row address is partitioned into a first portion and a second portion. The first portion of the row address is provided via an address bus and a first active command is provided via a command bus the DRAM. The second portion of the row address is provided via the address bus and a second active command is provided via the command bus to the DRAM, after the first active command is provided. The address bus is formed by a plurality of address lines, and a quantity of the address lines is smaller than the number of bits of the row address.
