    • A DRAM control circuit, having a second counter 12 which counts the number of times of generation of a refresh request signal generated by a first timer circuit 100, a set value register 13 which holds the maximum number of reservations for refreshing a DRAM 52, and a second comparator 14 which compares the count value of the counter 12 and a value held by the set value register 13, which cancels high-speed page mode and refreshes the DRAM 52 in a predetermined procedure only at a time when the second comparator 14 detects coincidence between the count value of the second counter 12 and a value held by the set value register 13. This configuration enables it to limit refreshing during high-speed page mode, while achieving a DRAM control circuit capable of operating in high-speed page mode more efficiently.
    • 一种DRAM控制电路,具有对由第一定时器电路100产生的刷新请求信号的产生次数进行计数的第二计数器12,保存用于刷新DRAM52的最大保留数的设定值寄存器13,以及 比较计数器12的计数值和由设定值寄存器13保持的值的第二比较器14,其仅在第二比较器14检测到的时刻以预定的过程来取消高速页面模式和刷新DRAM 52 第二计数器12的计数值与由设定值寄存器13保持的值之间的一致性。这种配置使其能够在高速页面模式期间限制刷新,同时实现能够以高速页面模式操作的DRAM控制电路 更有效率。
