Abstract
A method for dynamic random access memory (DRAM) control with adjustable page size, including the following steps. During power-up initialization, a DRAM type is identified and a page mask for the DRAM type is set. Upon receipt of a DRAM access, an adjustable page portion of an internal address for the prior DRAM access and an adjustable page portion of an internal address for a next DRAM access are respectively determined in accordance with the page mask. A first portion of the internal address for the prior DRAM access is compared to a first portion of the internal address for the next DRAM access, and the adjustable page portion of the internal address for the prior DRAM access is compared to the adjustable page portion of the internal address for the next DRAM access, to determine whether the next DRAM access is a page hit or miss.
