Abstract
Systems and methods for selecting pin functionality in memory controllers are provided. These memory controllers have pins that can be used to drive different types of signals, depending on the type of memory coupled to the memory controller. For example, pins can be used to drive clock signals or chip select signals. Accordingly, because different types of memory require different numbers of clock and chip select signals, the same memory controller can be advantageously used with different types of memory. Moreover, memory controller pins that would ordinarily go unused with some types of memory can now be used to increase the number of such memories that can be coupled to the memory controller.
