摘要： A memory device with a self-copy function includes a memory cell array having first and second banks, and a memory interface. The memory interface reads data from a memory area of the first bank corresponding to a source address contained in previously set self-copy information and writes the read data to a memory area of the second bank corresponding to a destination address contained in the self-copy information via a self-copy data path when a self-copy signal is activated by an external self-copy start request.

摘要： 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).
