  • DRAM having a reduced chip size
    Patent number: 6396763
    Abstract: A DDR-SDRAM has a plurality of banks of memory cells, one of which is selectively activated at a time. Each bank includes two memory cell plates, each of which is juxtaposed with a corresponding memory cell plate in another of the bank to form a memory cell plate pair for sharing an I/O amplifiers and a branch line of power source line. The number of I/O amplifiers and the width of the branch line can be reduced because the both of the memory cell plate pair are not activated at a time.
