Abstract: PURPOSE:To reduce the space on a circuit board and to facilitate the designing of the board by making access to DRAMs different in timing in the card when the DRAMs are accessed and preventing the DRAMs from operating at the same time. CONSTITUTION:A write row address is sent through the address bus 4 on the side of a system main body 2 and a converting circuit 7 sends it through the bus 4 on the side of a DRAM (dynamic random access memory) 1. Then the signal, the inverse of RAS of a control line 6 is lowered to LOW and then the converting circuit 7 holds the 1st signal, the inverse of RAS1 on the side of the DRAM 1 at LOW. Then the 2nd signal, the inverse of RAS2 is lowered to LOW with several nanoseconds delay to latch respective row addresses and then a column address is sent through the bus 4 on the side of the main body 2; and the converting circuit 7 sends it through the bus 4 on the side of the DRAM 1. Thus, when the DRAM 1 is accessed, the respective DRAMs are made different in timing in the card and the respective DRAMs are not simultaneously operated. Consequently, the space on the circuit board is reduced to facilitate the designing of the board.
