Abstract
A technique reduces cost, complexity and/or power consumption of a memory system by including intelligence in a memory buffer circuit of the memory system. An apparatus includes a memory buffer circuit configured to selectively operate in one of a plurality of modes. In a first mode, the memory buffer circuit is configured to interface to a first type of memory device, is configured to enable an input circuit of the memory buffer circuit, and is configured to drive on a terminal of a memory interface of the memory buffer circuit a version of a signal received by the input circuit during a memory operation. In a second mode, the memory buffer circuit is configured to interface to the first type of memory device, is configured to disable the input circuit, and is configured to drive a signal on the terminal during the memory operation.
