The 440MX chipset integrates a main memory controller that supports a 100 MHz, 64-bit
synchronous DRAM interface. The integrated DRAM controller drives a total of four rows of
memory (two double-sided SO-DIMMs) and supports 16-Mbit, 64-Mbit, and 128-Mbit DRAM
technology, and provides up to 256 Mbytes of total system memory.
