ABSTRACT:
Disclosed is a Rambus DRAM capable of reducing power consumption and layout area by enabling data read/write control signal of accessed memory bank only, in a top memory bank and a bottom memory bank. The disclosed comprises: a top and a bottom memory bank blocks including a plurality of unit memory banks, respectively; and a data read/write control signal generation block for generating a top data write control signal and a top data read control signal to the top memory bank block and a bottom data write control signal and a bottom data read control signal to the bottom memory bank block, thereby controlling the top memory bank block and the bottom memory bank block to separately operate in data read/write operations.
