One embodiment of the present invention provides a system that uses encoded memory control signals to reduce pin count on chips that generate and drive memory control signals. During operation, the system receives encoded memory control signals from a memory controller, wherein the memory control signals were encoded to reduce the number of memory control signals, and wherein the encoded memory control signals are received at a buffer chip, which is external to the memory controller. Next, the system decodes the encoded memory control signals on the buffer chip to restore the memory control signals, and then drives the memory control signals from the buffer chip to corresponding memory modules in the system memory. By transferring the memory control signals in encoded form from the memory controller to the buffer chip, fewer pins are required on both the memory controller chip and the buffer chip.
