Abstract
A multi-port memory device including a plurality of ports, a plurality of banks and a plurality of bank controllers, wherein all of the bank controllers share all of the ports, the device includes a phase locked loop (PLL) unit for generating an internal clock signal; a delay unit, provided in each bank controller, for generating first and second delayed clock signals by delaying the internal clock signal; a serializer, provided in each bank controller, for receiving a plurality of parallel data from all of the ports and fitting the parallel data for a corresponding data frame in response to the first delayed clock signal; and a command decoder, provided in each bank controller, for decoding output data of the serializer to generate command signals in response to the second delayed clock signal.
