Abstract
A memory controller is configured with a PLD, and includes an input pin for receiving an input of a control signal from the outside of a memory module, and input pin terminals for receiving inputs of electric signals. The memory controller controls the operation of a plurality of memory units in response to a control signal that has been passed through a filter circuit capable of adjusting cutoff frequency depending on the electric signals. Thus, noise is removed without modifying the design of the filter circuit depending on the system in which the memory module is incorporated.
