ABSTRACT:
A dual port memory device converts an address and a control signal, which are inputted via a first port and conform to a first type memory interface, into an address and a control signal which conform to a second type memory interface, to access a memory array. The dual port memory device accesses a memory array based on an address and a control signal which are inputted via a second port and conform to the second type memory interface. The dual port memory device accesses a memory array according to the first type memory interface or the second type memory interface in response to a selecting signal. Therefore, the dual port memory device can be coupled to a processor with a first interface (e.g., PSRAM or SRAM interface) and a processor with a second interface (e.g., SDRAM interface).
