MEMORY DEVICE AND CONTROL METHOD THEREOF

摘要

A memory device is provided. The memory device includes a plurality of memory banks, at least one buffer bank and a controller. Each memory bank has a bank index and includes a plurality of bank memory units for storing data associated with a logical address corresponding to the bank index. The buffer bank includes a plurality of buffer memory units. The controller receives a read command and a write command in a first clock cycle, wherein the read command and the write command are requesting to access a specific memory bank among the memory banks. If an access request of the read command and the write command exceeds a bandwidth limitation of the specific memory bank, the controller utilizes the buffer bank to accomplish the read command and the write command.
