WRAPPER CIRCUIT AND METHOD FOR INTERFACING BETWEEN NON-MUXED TYPE MEMORY CONTROLLER AND MUXED TYPE MEMORY

PROBLEM TO BE SOLVED: To provide a wrapper circuit for interfacing a non-muxed type memory controller and a muxed memory. SOLUTION: The wrapper circuit includes a select circuit which selects one of write data and an address input from a memory controller having an address port and a data port that are distinct from each other according to a first control signal and an input/output buffer which outputs the selected one of the written data and the address to a memory having an address port and a data port that are not distinct from each other, receives input of read data from the memory to provide the read data to the memory controller. Thus, the wrapper circuit may easily control a memory, in which the address port and the data port are not distinct from each other, using a memory controller with which the address port and the data port are distinct.
