Abstract
According to one embodiment, a semiconductor memory device includes a memory array, an address counter, an address detecting circuit and a control circuit. The memory array has a plurality of memory cells arranged at crossing positions of word lines and bit lines. The address counter increments an address including a row address and a column address in synchronism with a clock to sequentially output the incremented addresses. The address detecting circuit detects an address previous to an address including a row address to which the row address is switched at the address output from the address counter to output a detection signal. The control circuit performs a precharging operation to the bit lines connected to the memory cells according to the detection signal output from the address detecting circuit.
