PURPOSE:To perform high-speed access, by starting a page mode cycle and accessing a memory if a new column address is the same as before when column addresses are monitored. CONSTITUTION:When a new column address supplied during access to the memory is the same as the output of a latch as the last column address, a comparator 3 generates a coincidence signal, which allows the mode transition of a controller 5 to a page mode, and an address is determined only by specifying a new row address of a memory element. Thus, the access is speeded up. |
