ABSTRACT:
A memory controller converts controller output signals output from a controller into memory input signals according to the operation specifications of memory chips to operate, and outputs the resultant to the memory chips through a common bus. The memory controller also receives memory output signals output from the memory chips through the common bus, and converts the received signals into controller input signals receivable to the controller. This allows the single memory controller to access the plurality of types of memory chips. As a result, the memory controller can be reduced in chip size, lowering the cost of the memory system.
